It's not just about money, although if gas prices really rise it could pay off down the road. It's about using less oil, for the environment, for national security, and because EVs are quiet, torquey down low, and novel.Something like the motorcycle would be great for commuting, although depending on the price tag I'm not sure how much you would actually save. I ride an R1 (the same bike I know you have had) and routinely get @30mpg. I think the hard part for most of America to swallow would be spending $15K+ on a vehicle that can't make road trips or serve all of your needs. Also, I have never seen any electric vehicles address the idea of a truck. There are just a lot of hurdles to purely electric vehicles that aren't simple to address or implement, especially to replace an industry with an immense infrastructure...all politics aside.
With regard to never haven seen an EV truck, that just shows that you haven't been looking. Ford offered a Ranger EV and Chevy an S-10 EV back when CARB required a token number of ZEVs to be sold. Additionally, companies are producing (as in today) short range EV semi-tractors for use at ports for moving around trailers, and there also exist at least in prototype form EV delivery vans and the like from the Transit Connect EV to full-size commercial vehicles (see below).
