EVs still have peak operational variables, things like heat. Having 2 gears solves the heat problems. Quicker acceleration and better efficiency. Just because it's expensive right now doesn't mean you won't continue to see them on high end vehicle and start to trickle into the mid range stuff.

Why is a electric motor overheating dangerous? Surely any electric car is going to have a system to throttle itself if overheating is an issue, and it will need that with or without gears.

The fastest accelerating electric cars are single speed, presumably because it's not worth changing gear when you only have 2 seconds.

I can see why it might be useful in specific product categories, but when it's not helpful for price or performance or reliability, that's going to continue to be niche. The real problem electric cars need to solve right now is cost and a gearbox isn't helping with that.

Nobody buys a 600bhp car to have itself throttle its performance. Well nobody with half a brain which says a lot about Tesla sales.

As far as acceleration is concerned most drivers who care about performance don't really care about 0-60 these days. It's about 70-120 and how they perform at the upper end. Single gear EVe suck at anything above those speeds. Only the high end models are fast enough to hide it.

Also acceleration isn't power limited. It's traction. It's not gear shift or power that keeps everything with normal sized tires at about 2.5.

A second or third gear in sport cars will be a thing. There are plenty of valid use cases once you make it past, "this is a boring commute appliance".
