How is it self driving if it’s on fucking tracks my guy?

Edit to say I get that “tracks” may not literally be required, but that’s besides the point

Edit2 note that self driving as a term has been agreed to convey autonomous driving. If you’re thinking of trams or trains as self driving than you need to use the fucking correct terminology of self propelled. You cannot redefine a term because you failed the problem or don’t want to attempt it
