absolutely not a limit is just that a limit and safer driving could be anywhere slower than that at times. In fog or heavy rain or high winds or icy and snowy conditions.
Took my family on holiday once and was caught in a torrential downpour causing flash flooding. The wipers were barely clearing the windscreen and there was a great danger of aquaplaning so I slowed down to 40mph in the inside lane and was disgusted to be overtaken by HGVs still driving to their max limited 60mph.
Same with fog. I slow down way under the limit while others continue to blast past at stupid speeds.
Safe driving isn't all about speed its all about appropriate speed and awareness.
