I would actually be interested.
I can't count all the times that I've had a 12-20 mile commute and despite my best intentions, I never rode to work.
An electric bike would dramatically reduce the effort. From getting dressed for a ride to actual effort to being sweaty at work. Maybe lowering the effort to do it would get me going.
Yes it's kinda weak sauce but it's also way better for the body and the world than driving. I really can't fault it.
I do think a tax incentive based on alternative commuter days would be less divisive. There's tons of people who manage big bike commutes on a regular bike and have been doing it for years. They need some kickback too.
