Taking advantage of bike lanes in cities is a huge advantage for a battery/motor assisted bicycle, but I do most of what you describe with a Yamaha XT250. Just don't go out if it looks like rain. You have your helmet and pack a raincoat in case you get unlucky. To carry some groceries you could easily rig a small rack on the back where you can attach/detach a grated plastic crate. Then put some in a backpack.

I don't do all of that but I could easily do it. I'm at the stage of my life where owning a small truck like a Tacoma or Maverick makes a lot of sense due to the utility. You have a lot of good ideas. On your negatives for EVs, I'd say walking infrastructure can't really occur without living in a dense city. Pipedream otherwise. Acceleration is less of a problem rather than people not paying attention at all, smartphones. As far as the weight, that will go down over time as solid state batteries come around.

I wouldn't trade my motorcycle for an EV motorcycle without significant advances, I also don't see interstate towing being overtaken by EVs anytime soon. You just can't beat a diesel for that whether it be in a pickup, van, or semi, and it will be tough to do so. Yet EVs in general are definitely inevitable as they are already better for countywide travel.
