Yes, why bother with incremental change that's already possible and well understood when we can go all-in on a technology that's not yet proven and will require cars to get even more expensive and complicated.
This is the same thinking that got everyone chasing "Hyperloop" pixie dust instead of just putting in the work to build high speed rail.
> Yes, let's just focus on small stuff we already do
No, you don't
> automated cars with less human error.
The comment you replied to already noted that this has no effect on existing cars, of which many magnitudes more exist than automated cars (those do not exist on the road, not to the degree that is proposed).
> Sometimes I can't even on this website with supposedly some of the smartest folks.
Every driver has a cellphone in their pocket, I'm sure it's more than possible to integrate people with modern vehicles in a mesh net to older vehicles by using an app or something. It's not hard to think about, c'mon now. What website am I on ffs?
The problem is reliability. The cellphone is not constantly connected to a network, depending on its location, battery, age of electronics, software updates,... You would need a system that works with a mesh with holes. Not much better than today's situation i would guess.
