if you make dedicated lanes for bus you might as well have trams, IMO

also, it's no big deal to have a killswitch onboard for passengers to pull if there is a problem with the tram not stopping, that's the thing, there is always gonna be passengers for this

idk anyhow i just like trams and trains because they aren't bumpy and are easy to electrify so they don't smell either, and don't require stupid giant lithium batteries and have all that downtime to charge

IMO self driving cars and trucks is a fad that will fade once enough fatalities happen... there will eventually be a class action suit against it and the cost of legal defense will make it impractical
