SUMMARY

This discussion explores the implications of applying mathematical reasoning to traffic laws in the United States, particularly regarding turning maneuvers at intersections. The idea of legalizing left turns on red and straight-through maneuvers on red is proposed, contingent on the legality of U-turns. Additionally, the conversation suggests a need for a speed limit system based on driver aptitude and vehicle capability, aiming to reduce accidents caused by speed differentials. The feasibility of enforcing such a system is questioned, highlighting potential challenges in implementation.

PREREQUISITES
  • Understanding of traffic laws and regulations in the United States
  • Familiarity with concepts of vehicle dynamics and speed limits
  • Knowledge of mathematical reasoning and its applications in legal contexts
  • Awareness of traffic safety statistics and accident causation factors
NEXT STEPS
  • Research the legal framework surrounding U-turns and left turns on red in various states
  • Explore the implications of driver aptitude tests on traffic safety and enforcement
  • Investigate mathematical models for traffic flow and accident prediction
  • Examine existing speed limit regulations and proposals for reform based on vehicle performance
USEFUL FOR

This discussion is beneficial for traffic law policymakers, transportation safety researchers, and automotive engineers interested in the intersection of legal frameworks and mathematical reasoning in traffic management.

Some time ago I had a thought regarding turning rules in the US, back when right turn on (a) red (light - unless otherwise marked) was becoming universal.

If U-turn was legal on the cross street, then by smoothing out a sequence of legal maneuvers:

- left turn on red should be legal (right on red + U-turn)
- straight through on red should be legal (right on red + U-turn + right on green)

Needless to say I've never been willing to test in court how 'virtual' each maneuver can be to have legal standing.

So, can anyone add to to this list of what would follow if mathematical reasoning were applied to traffic laws? (any type of traffic law, any type of formal reasoning)

Can I do a succession of 5 consecutive U-Turns (4 Loops + 1 U) instead of doing 1? Or are loops suppressed because they would take longer and not be as prudent...

I have always felt that there should be a scale of speed limits. You should have to take a mental/reaction aptitude test, and have your vehicle rated for specific maximum speeds, and be given a special limit based on it.

This way you avoid grannies in top-heavy SUV's from barreling down a highway at 70mph, and professional race car drivers in the Z06's can go 180mph.

But as to your original intent :

If the center lane is dashed (thus allowing for passing) and there are no oncoming cars, and traffic is backed up in my lane (construction?), can I just drive for as long as I want in the oncoming lane, "passing" everyone legally?

Most fatalities are occur in accidents where there is a large speed differential. Your system would increase the number of cars traveling at higher differentials. Plus, how would anyone enforce such a system?
