I've been considering getting a few of these but I've got one question about them...I can see you using them on pavements to allow the public to get past, but if for example, you're on a one way road and you can't park on the correct side of the road but there's a space directly opposite, can they be used as ramps for cars to get over the hoses if you decide to have them going across the road??
Cheers,
Dave
