- innocenat 9y agoSteel-on-Steel rail are generally also most energy efficient compared to rubber-tyred vehicle. And IIRC, one of the most expensive part of rail building is the dedicated right of way, so if you are also doing that for self driving vehicle then might as well as go for rail (if there's demand, that is)
