Emergency vehicles should be in the road. Cars causing an obstruction to emergency vehicles on the road simply need removing.
Two questions there though Alan.
One is that the technology works, and the safety measures work - and whether they'll be maintained to be always in working condition.
I would suggest that you direct that question to the inventor, one "Yannick Read, 47, of the Environmental Transport Association" possibly via the ETA, rather than to me. My role was in placing the link to the report in this forum for discussion as I thought it would be of interest to denizens of this hole. I am not responsible for its claimed limits of operation. Some have questioned whether the report is correct: Fair enough, but expecting anyone on this forum to be responsible for the adequacy of testing is a bit odd.
JohnW wrote:The other is whether cars causing an obstruction to emergency vehicles will actually be removed. It won't happen - ask a pavement parking motorist to consider others? - never. Find any one in authority with the will and authority to do it? - never. In a perfect world there'd be someone on site quickly to sort the situation out - but it's not a perfect world - if it was, there'd be no cars/vans on the footpath in the first place.
Expecting any solution to be used perfectly is naive. This is apparently an alternative to bollards, which may be useful in some situations. Obviously if a council placed these along all pavement edges everywhere, people would not be able to access their own properties across the pavement (currently legal). However if the specifications are as reported, I can see a use for these in some circumstances - such as to defend flexible wands for example (i.e. place them under the wands so that vehicles driving into them get punctured). I would never see them as a magic bullet, simply one more tool. Of course we could always just give up and allow motorists to park anywhere, but IMO there is too much of that already. However "it won't happen" is over stating the case as cars do get removed for obstruction; I have even witnessed this myself and know it isn't just a you-tube stunt.
