The best solution would be to require actual driving instruction to get a license.
I drive I-70 at least 6 times a year and 90% of the traffic problems are created by idiots that don't know how to drive -- especially in mountain terrain.
Tip#1: Your brake is primarily for coming to a full stop and for unexpected/emergency maneuvers. It is not for minor adjustments in speed and under no circumstances to maintain speed when going down a steep grade (e.g. Eisenhower).
The number of idiots riding their brake down steep grades is maddening. You should never have to apply your break going down Eisenhower or most of the grades on I-70. If you don't know what engine braking is, you shouldn't be on the road (though you are improving the economy by increasing the sales of break pads!).
Tip#2: More on braking. See that tunnel or that curve? If you feel the need to break before entering them, you are driving too fast for your skill, conditions or your overweight and top heavy urban assault vehicle (with exception of curves marked with lower speed limits than the rest of the road). Slow down to a consistent speed you and your vehicle can handle. Traveling at an inconsistent speed in these situations creates a butterfly effect that causes most non-accident related traffic problems.
Tip#3: Related to #2. See that right lane? Be in it unless you are passing.
