Somehow I missed that video. I love watching enginerds in full-on soak tests. Back in my day, it was environmental chambers. Checking on our digital boards in specialized hot rooms. It was the only time my big Megacorp allowed us to wear shorts at work.
Don’t worry, we still have that! My company builds hydraulic test systems and some of them are designed to go inside a whole hot room. Unfortunately I can’t share more but there’s some cool stuff.

I'm a tad concerned about the 90mph governor. I'd like to know the reasoning behind it. I don't want/need to go over 90, but I do want authority at 75 to quickly accelerate if needed on the highway. Being that close to "limit" of the truck isn't confidence inspiring.

There was one reviewer that claimed it still had punch at high speeds, but that's one person and I don't know what they consider "punch" (not sure that's even the word they used, but my point still stands).

If there is still strong acceleration from 75-85mph, why do the motors stop at 90mph? I understand it would be wildly inefficient, and illegal on public roads. However, both of those issues are between me and god. I don't need a sports car, but I want confidence while driving at AZ highway speeds.
Since I don’t have any data, this is just theory from my electric vehicle design and motor experience
  1. Power consumption from drag is proportional to velocity cubed, so any extra speed really hurts efficiency
  2. As RPM increases in a motor, it generates more back EMF, eventually reaching the voltage limit of the inverter. At this point, the motor can no longer maintain the same current and torque as RPM continues to increase. Field weakening can be used to counteract some of the motor’s magnetic flux, typically by applying current in the opposite direction of the permanent-magnet field. This reduces back EMF and allows the motor to reach higher RPM, but with reduced available torque and lower efficiency. So there will be some big falloff above a certain rpm. It may be better to just govern the motor than deal with this
  3. Highways are limited to 80mph in the US, with a lot of states keeping to 70. 90 allows you to pass people while barely breaking the law

How many of you would pull the trigger if they have a Carvana type experience where you get to test drive it before actually taking it, also have a no questions asked 7 day return for a full refund. If they would offer that I think many on the fence people would commit. Would you?
Carvana does not sell new untitled cars. a "7 day return" is an impossible ask for any make.

I'd want to see how the 1-pedal regenerative braking feels. I like the Toyota HEV & PHEV regenerative braking & I've owned 2 of them. I've rented a number of HEV's on business trips recently, & quite frankly the non-Toyota ones suck. None of them were 1-pedal, but it still makes me wary.

Actually, some of the luxury brands had a subscription program where you could take any car from their fleet, use it as long or as little as you wanted, and exchange it at any time for another ride. Obviously not an inexpensive subscription. The terms varied by OEM.

I think all those experiments failed. Volvo almost lured me into an XC40 subscription. But it was like $8,000 a year, and I'm better off owning. But that covered maintenance and insurance too.
