It really depends on your definition, pretty much every car for the past 50 years has been computerized. If what you're really after is an ev with no lockouts there are plenty of ev's where the only lockouts are to ensure you don't do anything stupid (no over-discharge destroying the battery for slightly more range, etc) But if you're after complete control you'll find that in ev conversions with dedicated speed controllers will give you complete control, so you can shoot yourself in the foot if need be.
