Challenges in Self-Driving Car Development

I do. It's the sub-panel that has the CB for the majority of my home's circuits with the exception of the two HVAC units.

I could have run my EV charging off that sub-panel but it was a cleaner installation to run it out, through the crawlspace, to the main.


No! There is too much misinformation out there on the subject. People read it and believe it. Living with an EV is very different from what the common knowledge makes it out to be.
If somebody bases their decision on an EV based on a one line response to a joke, I'm surprised they can eve operate a phone or computer to a level that allows them to read it in the first place.
 
Didn't you get the memo? The tribes switched sides on Tesla.
I got curious about that a few weeks ago when I was arranging the rental. A number of studies indicate that liberals were the predominant EV purchasers, which made some "intuitive" sense. But there were others which placed is as a function of income and career/professional status, suggesting that there may be more GOP owners than Dems.

I guess the drop in sales tells the ultimate story.
 
The vandalism was occurring long before the recent left wing crazies. You can watch sentry vids on YT from years ago with people keying Teslas. Only difference back then they were right wing nuts and weren’t stupid enough to vandalize Tesla service centers.

As far as super charging. I’ve had Teslas for 3 years and only super charged twice. Did it once on the S to see if I had free super charging. Did it once on the X at the service center after maint. Just not needed unless you road trip. I’ll be the first to tell you I would never road trip my cars unless it’s an emergency. My time is too valuable to sit there in a bad part of town charging. I will say though it won’t be long before all that changes. Chinese companies (I think BYD) have developed a battery that can fully charge in 5 minutes. Won’t be long before Tesla catches up.

Not really. A conservative may avoid buying a Tesla because they fear being targeted, so it’s not only liberals avoiding the purchase.
 
Drift into political leanings aside (and I would not like to see yet another thread derailed by silliness)

Agreed. But some people just can't resist.

I’m not likely to buy a Tesla when I buy aN EV. It has nothing to do with Musk.

Right now I would ONLY buy a Tesla, for the simple reason of the supercharger network. That may change in a few years, but currently it is a huge advantage. Probably the single smartest decision Musk made.

It’s been about a year since I traded the Tesla for a ford ev. Zero regrets.
 
You know that the Supercharger network serves makes other than Tesla now, right?

In theory yes, but it is far from universal. there are plenty of yabbuts that will take time to sort out. And Tesla charges higher rates for non-Teslas.


Road trips with EV's are a PITA. The Tesla charger network, integrated with the car nav software, makes it tolerable. I don't know how well other vehicle software does it. Can you put in a destination and get a charging plan that optimizes trip time?

Worse. Think about Thanksgiving travel. Everyone is heading 2 states away to see grandma. The lines at the charger at Bucee's are how long???
In addition to the optimization @Larry in TN mentioned, Tesla has developed a mobile Supercharger solution - Several Superchargers on a flatbed semi fed by their Megapack batteries, for temporary use in spots where they anticipate being under capacity for holiday travel.

There were some horrendous lines early on in Tesla's history, but more recently I haven't seen any stories about anyone not being able to charge in a timely fashion on a holiday travel weekend.

This. This right here is why these threads turn into the "zealotry". Those of us who know better, have heard people take the result of a "joke" and spout it as truth. There's so much misinformation about EVs, it's hard to take a "joke" lightly.

They were cutting the cords at Superchargers too.

I'll believe it when I see it. I've been hearing about these "super-batteries" for a long time, but nobody ever gets to the point where they're better than the status quo and mass-production ready. And like Elon said about this sort of thing at one point, Tesla buys more batteries than anyone else in the world - In fact, for a while there they used more lithium batteries than the rest of the world combined - and if you really have something that works, show it to them.

Yeah, but... I don't know that it'll even be "a few" years. I think Ford should be delivering vehicles with the NACS connector by now (or at least, I saw a news article that they've given away all of the free adapters...) and within ~2 years it'll be everybody. Recent model years have adapters available. Chrysler is a possible exception to both of those.

Of course, that's only for new cars, but they'll trickle out into the market and the pre-NACS EVs will die off eventually.

(not being arguementative or snarky) I would think that some enterprising person/company would find a way to retrofit older EVs (and, yes, I realize there is more involved than just the physical connector)

As i think I've indicated, I'm definitely not looking 'right now'. I have a 10 year old car which is fun to drive and has, by some miracle, turned out to be the most reliable car I have ever owned. I'll probably wait until it dies or something truly grabs my attention.
 
I wasn't trying to cherry-pick. I just thought that posting the links alone would be too user-unfriendly. Since you find the excerpts objectionable, I have removed them.
I’m offended by your submissive and apologetic demeanor.

The guy on Out of Spec Reviews has a vid somewhere on his YT channel with a review on it. Saw it first hand. They do a lot of battery swaps there as well. Takes just a few minutes.

Not seamless, as it is with Teslas, and not all Superchargers. Only V3 and V4 work with non-Teslas. The seamlessness should improve. It requires the coordination of the billing and authorization through the manufacturer.

And disaster areas, too. They brought them into the areas affected by the hurricanes and wildfires along with Starlink-driven hot spots so folks can communicate.

Should be able to. Would require the hardware and a new ECU. Not sure if it's worth it. You'd still want either the NACS->CCS or CCS->NACS adapter until the CCS stations fade away. Wouldn't improve the performance of charging with the CCS->NACS adapter now. Not sure if there's enough benefit for many to pay the cost of the retrofit. Since the current CCS port is larger, there should be plenty of room for the conversion.

There are other options for the redneck at heart:

Just for fun I ran the ABRP route plan for a Tesla Model S versus the Infiniti Q70S 5.6 I just bought and drove back from Detroit to Tulsa. I made the trip with two fuel stops and a total time in-transit of 14hrs (including a 30-minute stint while waiting out hail/thunderstorm at a Love's travel stop). The EV-route (happens to be the same route I took) adds another 4 stops (6 in total) and 2.5 hours to the trip. That probably would have made the difference in me stopping somewhere for the night (like St Louis or Springfield) versus pushing straight through, costing more time-in-transit and hotel money. All that to say I agree that road tripping in an EV would still suck, unless you were already planning to stop at multiple waypoints along the route to sight see. If the "journey is the destination" then an EV probably works okay; if the point of the trip is to get to the destination quickly then I'll take the ICE every time.
 
My Lyft driver last week sounded apologetic about driving a Tesla. I told him, "I don't judge people by what kind of car they drive,"

After five years, I have no idea what the quotes were!

A co-worker car-guy: "The car you drive makes a statement. Always."
Me: "What kind of statement does mine make?"
AC-WC-G: "That you don't give a **** what you drive."

He was right. And I never had to drive the gang to lunch.

Nauga,

Ah, the new combo a coffin and a car. At your local mortician
This is the closest you can get to renting a car as a visitor to Bermuda. It was a blast. And it beats the heck out of other options we've had through the decades - mopeds back in the day; scooters later. This is actually one of the bigger ones; most were three-wheelers with front to back seating. When I was choosing one, my wife said, "get the cheapest." But only until I showed her this one :D

It was also very convenient. The agency which rented them had locations all over the island with no cost for charging. That came in especially handy the day we spent in Hamilton. Not only free charging, but free parking!

Maybe. The really old ones aren't going to be worthwhile most likely; recent ones can use the adapter from the OEM, and the in-between ones are the target market, which isn't going to be huge. Most of those were purchased as city cars anyway, given the limitations of both the charging network and the cars themselves. For example, the Chevy Bolt maxes out at 50kW no matter how good the chargers is (and in reality, I never saw better than 38kW on mine when I had it).

The 2025 Ioniq has a NACS port and is on dealer lots today.
Glad to hear it. The initial plan, at least, was for about the first half of the OEMs to sign on to be shipping their 2025 models with the native NACS port and most everyone else in 2026, with a couple of stragglers (Fiat-Chrysler and maybe Mazda?) in 2027.

They do a lot of battery swaps there as well. Takes just a few minutes.
Tesla had that capability on the Model S and Model X. It took 90 seconds... But almost nobody used it, so they shut the station down and the Model 3 and Y are not capable of having the battery swapped quickly.

Except that Mazda does not currently make an EV. They have PHEV but can only do L1/L2 charging.

The EV-route (happens to be the same route I took) adds another 4 stops (6 in total) and 2.5 hours to the trip.
Not sure what I did differently. I get four stops total and 1:34 of charging. I ran from DTW airport to downtown Tulsa. 938 miles.

Interestingly, I ran it again on my Model 3 and got the same four charging stops but less time charging. Only 1:08. I don't have any experience with the Model S and didn't expect that. the Model S would have a higher consumption rate but I thought it had a larger battery, too. So, start with the 1:08 of charging and subtract the time you'd spend on two fuel stops, and any additional bathroom breaks, and that's the time penalty for driving a Model 3.

Could have been the year/model of Model S I chose at random. I dunno. That's still an extra 1:40 over what it took me in the gasser. Again, I'm not saying EVs can't do long XC trips, just that if the object is to go A to B quickly, they don't cut the mustard. If you are traveling with people who need to stop every 2 hours anyway or are stopping to sight see along the way, they likely do just fine.

I think you replied before I finished editing and adding the part about how the Model 3 would do on that trip. Nowhere near an extra 1:40.
