EVs are 30-40 times more expensive than an eBike. Manufacturing, shipping them, etc. is also harder and ramping up production will take more time.
To get the same gas reduction bang for the buck those top 10% would need to be consuming 30-40x more gas.
And as others have pointed out, those high gas users are probably not great markets for current EVs anyways. Current EVs work because most people don't need to use too much energy in 1 day, so they can fill up enough for a days worth of driving overnight. High gas users, almost by definition, will be using up a lot more energy, which can likely only be sustained by using gas cars, which can refuel the energy in minutes.
