In Victoria Australia they are talking about implementing zero tolerance on speeding - 1 km/h over the limit and you can be fined. The argument is that speedo's all read fast so it should not be a concern if you stick to the indicated speed limit as shown by your speedo. South Africa has also mentioned doing this I believe?
Another topic under discussion is having two cameras placed a known distance apart and taking photos of each and every number plate that passes through. So if they are 100km apart and you arrive at the next one in 50 minutes they know you have been doing more than 100km/h ? Very big brotherish, unless you pull over for a break every 15 mins and drive like crazy between breaks

To go back to the original question, the safe cruising speed will vary from car to car as already stated.
The more instrumentation you have the better able you are to make an intelligent assessment of whats happening in the engine. As a minimum you need an oil temperature guage but a measure of air temperature at the throttle body, oil pressure and exhaust gas temperature are also helpful. Also please note that the standard water temperature guage will read normal in the range between 74 degrees centigrade and 94 degrees centigrade, so it is hardly a precision instrument from which to gleen useful information.
Once you have this information it is easy to determine a safe cruising speed but even that will vary from day to day depending on ambient temperature.
For an absolutely accurate speedometer you could consider an SPA Microprocessor which performs many additional functions.

I drove to Cornwall, 365 miles, in about 4.5 hours.
A good portion of that was at 30-40mph in cornwall itself
THe subaru Legacy (in a record breaking attempt) did over 100,000 miles at an average speed of 143 mph I think, so a few hours at 100mph isn't going to be a problem.

152 indicated is probably barely 140 mph. The speedos on many are VERY optimistic at these sorts of speeds. Whatever, the ECU on the MY99/00 does have a speed limiter which progressively cuts the boost. It appears that most of the others have it too.
