From my visits to Paris, I'd say the biggest detriment to driving there is other drivers. It's common to see parked cars completely blocked in (cars in front and behind leaving literally a centimeter of space between bumpers), and an obscenely high percentage of cars have all sorts of scuffs and bumps (presumably from having to force their way out of parking spaces when blocked in). I'm no car nut, but I wouldn't dream of taking my own car there.
