  • The photo shows the car getting a 16kW charge rate while driving at 5mph. So you could get 16kWh of energy if you drove on this kind of road for an entire hour, at 5mph. Pretty worthless.

    I’d love to know what sort of charge rate you’d get while driving at 35 mph, the standard speed on surface streets. Based on what little I know about inductive charging, I’d guess that the charge rate will be dramatically slower.

    But if you get even 5kW while driving at 35 mph, I think that’d actually be pretty useful. Assuming that you get a significant efficiency increase at such a speed (5 mi/kWh seems reasonable), then going 35mph would use up 7KwH of energy per hour of driving. If you can restore 5 of those kWh from the roadway itself, you’re getting back over 70% of your energy usage while you drive.

    The question then, however, is “How efficient is the energy transfer?” Because I doubt it’ll be very good. It’ll be rather expensive to pay for that “charge while you drive” power if you’re only getting 30-40% efficiency (at a guess). Some folks might be willing to pay that premium, but by the time this tech is ready to go to market, I imagine most people won’t really feel the need to “charge while you drive”.


  • I’ve owned Teslas for almost five and a half years, and the service I’ve received has been near-universally exemplary. And my 2018 Model 3 needed a lot of service.

    Over my 5-year ownership of that Model 3, it had 12 unscheduled service visits, including Mobile Service. Every single one was an entirely positive experience. The sole complaint I would lodge is that it took longer than I would have liked to get my car fixed after the inverter blew early last year. It would have taken 10 days, but the replacement inverter my local service center got from Tesla was also bad, so they had to wait to get a second one in. Overall it took 22 days to get back into my car. During the first week I got around on free Uber credits from Tesla, but they eventually managed to get me loaner, which I used for the other two weeks.

    I now own a 2023 Model Y, and it’s needed service once, for a rattle triggered by particular frequencies coming from the sound system. The reason I only said “near-universally exemplary” in my opening paragraph is that they actually failed to fix the problem on the first service visit. Shortly after I got back in my car, I heard the rattle again. I texted my service rep and she said to put in another service request, which I did, and scheduled it for two days later. That time, she and another tech worked closely with me to come up with a perfectly reliable method of repeating the rattle, and also helped me discover that it wasn’t actually coming directly from the speaker, but rather from the trim near the speaker.

    The problem ended up being some broken clips that were resonating at those frequencies. Replacing those clips with intact ones fixed the rattle.

    Every interaction I’ve had with Tesla service staff has been positive. They’ve all been gracious and helpful, never rude. They’re generally quite prompt to respond to texts sent through the Tesla app (which is your primary point of contact with service if you’re not physically present at the service center), and they’ve kept me up to date on essential progress during longer service visits (which is how I know they got a bad inverter 10 days into the repair of my Model 3). And note that this has been at three different Tesla Service Centers in the LA area: Burbank, Costa Mesa, and West Covina.











  • This is straight up wrong. It’s completely safe to charge to 100% occasionally. What you need to avoid is leaving your battery at 100% frequently or for extended periods. What matters is time spent at 100%.

    Don’t charge to 100% every night, and don’t charge to 100% and then leave the car alone for a week. Feel free to charge to 100% before leaving on a road trip, and overnight at your hotels on said road trip, though. And the occasional 100% charge at a DCFC is also fine, if the charger’s not busy and it’ll help you skip a charging stop later.
