BTW, there's a major problem with Race 7. The course you're driving in not in Mexico. It's actually the US Grand Prix that was hosted in Long Beach, California, which judging by the course layout was Long Beach West Course.
@DeStCyr true. many of Taito's games in the mid 80s were ostensibly infamous for having their final stages become "points of no continues" like Darius 1 and Exzisus. Operation Wolf, Operation Thunderbolt, and 1990's Space Gun put a twist to it by adding the parameter that if all of the hostages die (either by the enemy or by your accidental doing by killing them) you would not be able to continue.
@DeStCyr that's especially true with the final race in Suzuka (Japan) since it's a "point of no continues", meaning that if you run out of time, you will not be allowed to continue.
IKR? If only they port this version, sound and type of steering on the Super NES, which they should have done back then in 1994, and on Nintendo DS this year, they would have let you continue on Suzuka! But no they didn't! That is what sucked about it! )X
