Let's see, 85-62 is 23. Is it your opinion that most drivers can not miss a stopped car on a 4 lane road when driving 23 MPH? And the fault is the slow drivers?

It’s not about fault. It’s about increasing the chance of being in an accident.

According to state and federal studies, drivers that are driving significantly below the average speed are the ones that are most likely to get involved in an accident. Studies show that the most accidents occur when the driver is driving at 10 mph slower than the speed limit. So someone going 45 in a 55 has a bigger chance of getting into an accident than someone driving at 65-70 mph.

The main problem on roads that causes accidents is the differences in speed, rather than speed itself. While some people are going faster than other, some go slower which causes the traffic to flow unevenly. If the speeds limits are raised to comply with the actual travel speeds, the roads become safer, because the traffic now flows more evenly and people start going to the same speeds. This actually shows that drivers are not affected by the speed limits that much, but rather slow drivers. The National Highway Traffic Safety Administration (NHTSA) Says that only 30% of the accidents that are fatal are accidents in which the driver was speeding. This does not mean that the speeding actually is the cause of the accident. A study conducted by the Florida Department of Transportation says that accidents that were caused by speeding is actually 2.2%. This shows that if people drive faster all together it is actually safer than driving slow.

This is of zero surprise to me. Additionally, people driving too slow cause frustration for others resulting in loss of attention and more aggressive driving, particularly on single lane roads. Also, when driving faster, IMO, you pay even more attention and are more focused on what's going on around you. Poor road way design contribute to this with merging in on the left, turn lanes on the left side of highways and zero enforcement of not using the left lane for traveling.
And if yo do want to go slow, then there's nothing wrong with that. Adjust your route or at least have the courtesy to pull over. Absolutely loved seeing the signs in WA that stated you must pull off if you have more then 5 vehicles behind you. And they even provide short, right side slow down lanes so you can, safely. Bloodee brilliant.

Now Bert if we could just edumacate western Canadian drivers that where "passing lanes" are built on 2 lane routes, you don't floor it to 140 klicks so the line of 30 eleventeen vehicles that has been following you for an hour now cannot safely pass...

You must have been following me just the other day. Driving back home on a long winding single lane stretches with limited passing. The slow pokes hugging the center line, not giving others a clear look ahead on the broken line sections. And not moving over or slowing when being passed. Then got to the all too short double lane passing sections and sure enough those driving 5-10 under the whole time sped up so the rest of us can't pass efficiently. Would have been more frustrating had I not been in the Mrs. Audi. It took 5-6000 rpm and 160 km/hr to get around them. One dumb@$$ in a plumbing truck had 16 cars behind him and launched up to at least 120 at the passing lane after driving 85-90 the rest of the time in the 100 zones. That's 100% being an @$$ whole and dangerous.
