When driving, we can easily become too comfortable -- or even lazy -- and let our vision "settle" to just in front of the car. Unfortunately, your car needs a fair amount of stopping distance, even when driving at slow speeds.
It's best to keep your eyes fixed on where your car is going to be in the next 10 to 15 seconds in order to give yourself plenty of time to respond. (Most people focus only 5 seconds in front of their car!)
So, how far away is 10 to 15 seconds? According to the California Driver Handbook, 10 to 15 seconds (when driving in the city) is one city block while 10 to 15 seconds on the highway is about a quarter mile (that's a little less than half a kilometer).
By doing this, you'll still be paying attention to what's happening in front of your car but you'll have time to react more effectively.
