I'm not sure of the power curve for an electric vehicle, but if you add gearing, you introduce losses due to gearbox and you increase complexity. It's likely that it is not worth it in most applications. Only cars that used gearboxes in EV space (two speed) are usually intended to be able to hit 200mph so they need extremely wide rpm range from their electric motors. I know Rimac used one and Taycan (not surprising since Rimac is partly owned by Porsche). In Rimac case, they used the gearbox to improve 0-60 times but IIRC they are losing the gearbox for their new car.

Hybrids often use gearboxes. My wife's Prius was essentially an extremely heavy 70 HP equivalent EV. 0 to 10 it was a very fastest car although the acceleration curve flattened out fast and it was between hard and impossible to have enough traction to max it out. I don't hear much about prius transmissions being destroyed. Something interesting to think about, I wonder with demographic trends etc if 0 to 10 is a more useful measure of daily driver performance and experience than 0 to 60. My wife's car does 0 to 10 at every stop sign, and technically my car is faster at 0 to 60 but I only did that twice a day at most for the commute, for sportiness reasons I might prefer the worlds fastest 0 to 10 car over a theoretically faster 0 to 60 car.

Depends on how long the average on-ramp where you live is. 30-75 measured in distance instead of time would be a good measure where I live. Being able to gracefully merge no matter how bad of a situation the idiot in front of me leaves behind would be far more beneficial for day to day use than off the line speed.

  Prius has CVT, not a "gearbox".

  Hybrid is a completely different type of vehicle. Since they utilize an internal combustion engine, they suffer from the same power band issues that purely ICE cars have. This means that a hybrid does have a normal gearbox. I'm no expert on Priuses but my quick Google showed that Prius has the electric motors "after" the gearbox. This means that electric motor can assist turning of the wheel and that it can regenerate energy but it is not using the gearbox. One solution to this would be how diesel electric locomotives work. Internal combustion engine generates electricity that is then stored in the batteries and used to power the vehicle. These type of "hybrids" are not popular although I believe there is at least one available where it is used as a range extender.

Rimac already removed it form their vehicle unless I am very misinformed. The Tesla Roadster also doesn't have it. Basically almost non of the EV coming out have it. I assume Prosche just had the expertise for and it made it easier for them to hit the top level speeds.
