Roadblasters (NTSC, NES)

Why are there so many games about shooting cars, for the NES? Why was that a thing in the 80s?

Think about it; Mad Max, Knight Rider, Spy Hunter, Brum The Car... It's a conspiracy. 

Please note, this is an NTSC game, so it can only be played on an American, region-free or modded console! 

Condition: Good
