Hi Dave,
Have completed the survey, but I do think it needs to be a bit more in-depth.
For example, I think the 'wrongness' of speeding depends on circumstances eg doing 90 on a deserted night-time motorway is nowhere near as bad as screaming round a housing estate at 50, it's about the risk you are putting others at.
I'd quite happily have higher or no limits on motorways, especially say between 8pm and 6am but also happily be restricted further to 20 in all housing areas.
Also, it's not whether there are too many or too few police, but what they are looking for, I'd rather they left alone people driving well at 80 or 90 on the motorway and instead concentrated on speeding round built up areas; mobile phone users; drink-driving; driving dangerously (eg overtaking when they shouldn't; not in the correct lane; tail-gating; racing, etc); and, most importantly, stopping the unlicensed, uninsured, untaxed, un-MOT'd louts who are a danger to the rest of us.
