Better driver training, making the left lane a passing lane, get illegals off the road, enforce car inspection laws better, get driver training back in schools, increase jail time, but taxing won't do anything.
Hitting speeders in the pocketbook? Sure, it'll work. They obviously don't give a tinker's dam about the law and/or their fellow drivers, but about their pocketbooks? You bet they do. Hit them in the wallet. Higher fines/taxes/insurance premiums/deductibles. All fine by me.
