An approach to speeding / driving I think would be a monumental overhaul effort but well worth it in the end (figure ~10 years for full data on adoption / effects):

1. Tiered license system. For both motorcycles and cars / trucks / SUVs. You get the bottom tier license, you're stuck with anything under [hp / weight ratio limit or just hp limit]. 2nd tier gets you most stuff. 3rd tier gets you "performance" cars / trim packages. 4th tier gets you the sports cars / top of the line stuff. Similar with motorcycles - 300cc and under; 301cc - 750cc; 751cc - 1000cc; 1000cc+. Each tier comes with progressively more training requirements and stringent testing, but with an appropriate reduction in insurance costs, tickets, etc (along with granting you the ability to purchase the vehicle to begin with).

2. More frequent / stringent licensing in general. You get a DUI where you total your car, 3 others, half a storefront, a manhole cover somehow, and a traffic light? Buh bye license for ohhhhh, 10 years? Injure + kill someone and you're at fault? Lose your license for 2x the equivalent of how long you'd spend in jail for homicide - IF you don't go to jail for it. No buying it back either. Get caught riding dirty after the fact? Do not pass go, do not collect $200, right back to jail you go. License testing revamped to include more reversing, parking, parallel parking, merging, etc - and must be in an appropriate vehicle for the tier you're testing for. So if you know you're gonna go out and buy a turbo 'busa, no borrowing your girlfriend's moped for the keyhole test. Oh, and you have to get a truck / SUV qualifier kinda like your M1 is additional to your C license, or various commercial certs. So for those of you taking the license test in your mom's Civic and then buying an Escalade...no more of that either. License recertification - including full retesting - every 10 years for bottom tier, 8 years for mid tier, and 3-5 years for top / performance tiers.

3. Stiffer penalties, tied to, say, your car's value or your income, for various offenses. A speeding fine that costs $500 and an insurance bump is huge for someone making $50k a year. It's a "have my secretary pay my fine" for someone making $500k / year. It's not even a deterrent at that point. But if a reckless + speeding ticket costs, say, 20% of your car's value, and you have a Ferrari, well, that's gonna sting a lot more. (For example, I know someone clearing well into the 6 figures whose insurance was over $450 / month until recently. For one car. And it wasn't even an expensive luxury car, just American muscle.)

Of course, this is all mostly a pipe dream, and the legislation for it would probably end up so full of holes and exemptions as to be toothless, but hey...it'd probably be pretty damn effective at improving safety on the roads over time, to the point where speed limits would be of far lesser concern and we could work on removing them on most freeways...
