That having been said, I think it's a silly solution to expect bicycles to take over logistics. I think we can all agree however that if the only vehicles on the roads were for logistics and public benefit (e.g. ambulance) that'd be a massive improvement already.

Honestly trying to convince people that a full life can be lived with a bicycle feels a lot like the problem of the cave.
There's a whole world outside the parking lots, but too many people have never even seen it; just pictures of it on travel blogs about Amsterdam, and don't really think it's real.
Edit:
In addition to gears, batteries and motors are a thing.
A better solution would be to restrict traffic to commercial vehicles and only at certain times.
