Congratulations, you solved 1 issue related to car dependency and proliferation of huge vehicles, namely tailpipe emissions. Now the other 99 remain.
The solution to gas guzzling trucks is "boring", it's good trains, it's protected bike lanes in urban environments, it's smaller and safer cars in less dense environments, etc. But these things don't make Mr Musk money :)
I'm all for better transit, but it doesn't change that the trucks/SUVs keep selling and getting more polluting, and will do so for decades as part of the fleet
Hell, I just found out those same commuter lines extend all the way north to Kenosha, Wisconsin, and east to South Bend, Indiana, so into neighboring states. I did know people who commuted to Chicago from Indiana everyday so that's not too surprising.
Like I'd have to drive an hour and a half to get to Rockford from where I'm at in the far Chicago suburbs. And I'd be driving past a lot of corn fields to do so. So that's pretty far.

Sorry but they are not solutions to gas guzzling trucks. Trucks are utility vehicles which carry things. Materials to building sites, hay bales to fields, sports equpiment to the beach/river etc. These functions are not going to be replaced by bike lanes, trains, and small efficient cars.
The real solutions are hydrogen and synthetic fuel.
