Estonian word is “gaasipedaal”, which pretty much means “gas pedal”. Gasoline is “bensiin”, no relation to that. The word for pedal comes from accelerator regulating gas-mixture valve (throttle) in carburettor. “Gas-mixture” here is air mixed with atomised fuel.

It's also literally "gas pedal" in Russian, although more often people just say "gas". To accelerate is to "give gas".

The fuel itself is also "benzin" though. As I understand it's because benzene was the original anti-knocking additive.

Funny, in german it is "Gaspedal" and "Benzin". (And gas means gas/air in german, but I never made the connection. With cars, "gas" means "speed")
