I also want to add, the e-throttles we have in our cars were some of the very first mass produced. Remember the SLK was out in the mid 90's. E-throttles on today's cars (especially high performance) cars are different.

Just an example, I have a friend with a hellcat charger, if you tap his gas pedal the damn car will literally open up the throttle to some like 60% and make the wheels chirp. It definitely took some time to get use to a touchy pedal like that.
