Caravan sites and speed humps

Having just spent two weeks on CC sites we have now moved to a commercial site ( paid in full at time of booking by the way). Have noticed that the speed of vehicles on this site is much lower than CC sites. Why, quite simple, the site has a series of low speed bumps spaced at 25 metre intervals along all of the roads. This tactic really does slow down drivers, both solo and towing, so much that there really is no problem at all. Putting the odd bump at irregular intervals, as per the CC sites does nothing to slow traffic. Having them in series does, as by the time you have passed over one bump, you are approaching the next. Perhaps CC should trial this and see what happens.
