Super speed.
Either you would need to also think and react at super speeds, which mean the world would be agonizingly slow, or you would have normal speed reaction in which case you would crash and die.
There is also the option of super reaction time on demand, but in any case non of this matters as super speed would make the air as "thick" as a concrete wall so you would also need to me super strong and super durable.
This might not be a problem, since you could regulate how fast you run, in which case you could run as fast as a car which wouldn't necessarily require other super stats
