Speedway Fanatic

Haste
Whenever Speedway Fanatic crews a Vehicle, that Vehicle gains haste until end of turn.

Kaladesh Remastered

If her vehicle even has a brake, she couldn't tell you which pedal it is.

Speedway Fanatic's triggered ability triggers when it becomes tapped to activate a crew ability. Even if Speedway Fanatic leaves the battlefield before its triggered ability resolves, that Vehicle still gains haste until end of turn.
