The prupose of this thread is to find out what you would do in a no speed limit country or one that has a high speed limit.
If i was on the autobahn in my gf's bmw318 I would not take it over 80mph because it does not feel safe going that fast. (1989 bmw)
In my NSX i would feel fine cruising at 80 with a short burst to 150.
Please, tell us what you can do - not what you won't do:tongue:
There is a fundamental problem with US interstate speed limits that simply won't change anytime soon. All speed limits in the US are determined by the 85th percentile rule. That is, traffic in the area of which the speed limit is to be set is monitored and the speed limit becomes set to the speed at which 85% of the monitored cars are travelling. Turns out that 85% of drivers drive appropriately regardless of an imposed speed limit.
However US interstate speed limits are universally set at 65-75 MPH with 95% of interstate at 65 mph. These limits have NOT been calculated using the 85th percentile rule. As we all know, most people drive over 65 mph on the interstate and in SoCal most drive at about 70-80. Based on the use of the 85th percentile rule we can reasonably say that most people naturally drive at speeds which are "safe" for any given condition.
Speeding tickets are a huge revenue generator for the government. In addition, by giving so much latitude to most cars travelling over 65 mph it effectively allows police to stop anyone on the road at anytime since at least 85% of cars are travelling at more than 65 mph. The government really likes this idea and it will be very difficult to change
Most stretches of US interstates are just as safe and clear as any stretch of the Autobahn which, in many areas, imposes no speed limit. The fundamental difference is the quality of the driver, the car, and the ignorance of passing laws. On the Autobahn there is NEVER any passing on the right, ever. Lane discipline is strictly obeyed.
It is also ridiculous to state that a Ford Pinto is just as safe at 65 mph than an NSX. The NSX is a much safer car to drive at high speeds. Driving an NSX at 90 mph is not the same as driving a Pinto at 90 mph, period.
Therefore, at least on US interstates, 65 mph is an arbitrary number that simply does not reflect where "unsafe" speeds begin. Sure, the faster one drives the less safe it generally becomes, but where do you stop? Why not make the speed limits 50 mph then?
My conjecture is that since 85% of people drive at least 75 mph in SoCal that more accurately reflects the reasonable speed at which people should probably drive. IMO the only reason 85% don't drive even faster is because your chances of being pulled over are much higher at around 75 mph. In SoCal it is absolutely normal to see traffic moving at 80-85 mph. And in a high-performance car it would not be unreasonable to drive at around 90-100mph.
If I had to put a number on it personally I would say that on US interstates, assuming normal driving conditions, 85-95 mph would still be a "safe" speed and 95-110 mph would still be "safe" for a car like the NSX. Obviously, if lane discipline, etc. were practiced here it would be very safe.
These numbers are just personal opinion and conjecture.
