49. 1970 Ambulance
Whenever you use toy cars for their intended purpose (namely, crashing them into each other at SUPER high speeds!) there are bound to be one or two (or 10!) accidents. Mattel realized that early on and created this ambulance a few years after they produced their first rides. And, it's a good thing, too. Once they started creating tracks to race Hot Wheels (Criss Cross Crash anybody?), there were lots and lots of accidents taking place in homes around the world every day. So, this became a necessity.
