Trucks tend to have bigger alternators, so there is more power available. Even the most basic economy car has more than enough engine power, but the alternator can't deliver that power. The engine power instead mechanically goes through the transmission to the wheels. (in a hybrid car there are two alternators, one for the wheels and when for the rest of the electronics so the same problem exists)

the is solvable. you can buy bigger alternators, and in some cases there is enough room that they will even fit... However it is an additional upgrade that needs to be considered.

I don't disagree with what you're saying, but my point was that I don't know if power consumption is even relevant, considering what Comma are doing from a phone on a windshield. I don't know (I'm not an expert) but I don't think putting TPUs in trucks is a requirement for solving driving.

That's right the limitation is Data. You can't effectively use the extra compute if you don't have enough data to train a bigger neural network. https://jperla.medium.com/why-tesla-autopilot-ought-to-be-aw...

Do you actually have data to back that up? I read your article, which (no undue disrespect intended) looked to be full of unsubstantiated qualitative data/graphs and opinion. Are you an "expert"? Or are you trying to get medium clicks on your article/ purchases of your book?

I built self driving cars (at Lyft), including behavioral planning algorithms.

I have run these essays by engineers at Waymo, Lyft, Uber, Nuro, etc and they have verified all of the information (I've incorporated any feedback).

That's fair, although credentials != proof. Working for Waymo, Lyft, Uber, Nuro etc is a credential. The engineers you mentioned have verified that what you wrote fits with the method/ approach they think will work. There is a possibility that they're/ you're wrong.

(This isn't intended as a personal attack)

You asked for credentials...

Yeah fair, I wanted to see if you were full of shit, but you probably know more than me, and bickering and points scoring over stupid things is how hacker news turns into reddit, sorry.
