no, I don't think this is a good way, as then anybody has to deal with 
strange numbers that are different from on-the-ground.
I don't want to have numbers like 18,6411358 [mph] for a 30km/h limit in 
the database, and if we would start with that, it get's incredible ugly 
and difficult as soon as anybody starts rounding different.

On the other hand, if the britains would use SI units (that are afaik 
mostly metric), from my personal point of view that would be okay, but I 
don't think it's a useful approach.
