In the east and west, people are usually going 10-15 above (sometimes more in areas with even lower limits). This is great for city and state coffers because people who are only going 5-10 above the usual traffic speed (often to pass) are ticketed for 20, sometimes 25 over the limit. It's also a very easy way to profile certain groups because everyone is already speeding anyway. Realistic limits, or better yet, no speed limits might cause a few idiots to run off the road, but most slow drivers AND fast drivers go the speed they do because they are not comfortable with any faster. Keep right unless you are passing or have nowhere else to drive.
So, next time you get pulled over, remember that you're just being taxed further. Unless of course, you were weaving through traffic like an asshole and really deserved it. However, most people ticketed are just average Joes attempting to get from point A to point B. There's little evidence that speed limits actually increase 'safety'. The assholes who cut people off and fail to use turn signals are the real danger, not speeders.
Also, 'enforcing' these limits is a waste of time, waste of our money, and a danger to police officers who sit on the median and the drivers who panic when they see them.
50 mph? What the fuck? Should be more like 75 mph, AT LEAST.
2. Posted warnings suggesting minimum safe traveling speeds on United States interstate highways.
3. A single “local” sign with unusually small print posting a shockingly low limit. Used by small towns to supplement income, this sign is typically placed precisely at the town limit behind a large bush or other larger sign as a “speed transition point” on rural highways of much higher speed. (to find the secret speed limit sign, look roadside for the projecting front end of the police cruiser pointed in the direction you are currently traveling)
--Speed limit signs are still in black and white as there have been no real reasons to bother updating them to color since most people no longer use them.
