Perhaps they're just enjoying their automobile before it's back in the garage due to another problem

Boy racers are probably better at avoiding getting caught - until they wrap their car round a tree.

Now that a lot of LR Discoverys are old bangers, quite a few have been fitted with larger diameter agressive tread tyres by off-road enthusiasts. Larger rolling diameter = under-reading speedometer. So if the driver thinks they're OK doing 33 mph in a 30, they might really be doing 38 mph.

There's a few old Discos around here with big knobbly tyres and I agree they're probably not very nice at speed. But even at a lttle over 30 on the speedo, the real speed is closer to 40.

It's not just the knobbly tyres though - I think early Discos came as standard with a smaller diameter tyre than the 7.50's that many have been fitted with - which I think were optional on Discos and Defender 90's and standard on Defender 110's

I had a Land Rover 90 on 6.50 tyres and when I borrowed a set of 7.50's for it, the higher gearing was very noticeable - but I was aware of the speedo being 'slow' by about 15%.

If you're doing 32 mph in a 30 zone, you'd probably get away with it. If your speedo is under-reads a bit, that might be a real 34 mph - dodgy. But if you fit bigger tyres and the speed is another 15% more than that, you'd be doing a real 39 mph.

Come to think of it, boy racers often fit ultra low profile tyres on large diameter drug-dealer wheels. Despite the big wheels, the low profiles might give a smaller rolling diameter than the original manufaturer's wheels - so boy racers could be driving slower than whet their speedos say !

Audi A3 S3 FSI t Quattro

Failing to comply with traffic light signals

What a surprise.

Im surprised the vehicle most likely to speed isnt a Mazda 6 driven by feisty northern lady.

You're alluding to me aren't you

*claps sarcastically

Nice to know that fancy education wasnt a total waste of time.
