They are planning on making all cars in CA EV I think by some date in the future, but also having a massive problem with the power grid with even the EV cars they have now. In addition there are a bunch of other problems with EV cars, which cause them to almost be worse (or be worse) that gas using cars are currently.

As far as tunnels etc, you would only do it for main freeways, and by having layers it would allow no traffic for many metro-areas, which is becoming a larger and larger issue. The concept of tunnels (or multiple layers of freeway going up) has already been proposed to deal with that issue, so doing so in a way that allows you to capture Co2 would just be an extension of plans already being made.

Meanwhile they do have Co2 conversions to electricity, but they are large. I would post a link but it's easy to look up. Even if Co2 was only part of the process, the point is you would have a pretty endless supply that would be easy to collect, that could then be used and converted into electricity.

Getting rid of cars is a great idea, for primary transportation but we would need to drastically ramp up our public transportation to do so. It also requires a full overhaul while just converting freeways would reduce how much needed to be changed and could probably be done in a shorter period of time. Of course with the possible incoming auto-driven vehicles, you could have a fleet of auto-cars and not have people own them individually anymore (or not many people). That could allow for much more mass transportation (with busses etc literally picking you up at your door and creating routes on the spot based on people wanting to be picked up and let off). That could solve many problems as well, and work well with an EV system.

There are many solutions for sure, but alot of them are ...well fairly new as a possibility. I think the tunnel system with Co2 collection could have been completed now if they started 20 years ago, and most freeways could be 2-3 layers with a Co2 collecter on top by this point. That would solve the environmental issues, possibly provide alot of free electricity, and most importantly would have solved the insane traffic issues so many cities are experiencing lately.

Anyway, just random wonderings late at night lol.
