18 ms=0,018s

0,018*33=0,594m, At 100km/h your car travels almost 0.5 meters before your servos reacts
And it takes your servo about 100ms to actually go to full lock. Five times longer than the response time. And it took your body 200ms to react to what you were seeing.

Puts that latency into perspective - it is a tiny proportion of the cars response time.

We drive our cars by PREDICTING what is going to happen, not by responding to it. Our senses are very finely tuned.

The people that drive by reactions are the beginners that miss every apex by 2m. Latency makes no difference to that.
