Maybe all 3 Lotus games also used that trick to render their faux 3D graphics? Again, I wouldn't really know.
Not sure about that. I have Lotus Turbo Challenge (and other MD racers) and Street Racer used a technique that I haven't seen in any other racing game (on any format).

The only difference is the road texture is animated, which I guess is done with a looping, pre-rendered animation.
That seems more like it. The road textures were definately repetitive from what I remember (haven't played it in about 10 years).

Only one game used the SVP chip (to my knowledge), but there *may* have been other enhancer chips used in MD cartridges (32X / Sega 32 aside), as Codemasters released games in J-carts (the game cartridges had an extra 2 controller ports built in to it) and Sega's Sonic & Knuckles had the ability to plug in other game carts into the top of it (it was designed for Sonic 1 to 3, but other games could be plugged in and had the same effect as if Sonic 1 was plugged in).
