Threy don’t assist in producing smog so improved air quality and are much quieter.
Besides, all of those things are already being produced where they will be profitable.
Tampa just dropped their tram line project because they couldn’t save enough money. They’re replacing them with buses.
Brightline is getting ready to open their Orlando line & planning one to Jacksonville & Tampa.
Like hear me out: what we need is Full Self-driving ride sharing so ppl don’t have to own a car to get anywhere they want. Just call a self-driving taxi & go to work. This would make trains more convenient too (would always have a cheap “rental car” ready at each stop so people are less-incentivized to take the highway) and significantly decrease the amount of cars overall.
