A multi-storey car park in New York has recently collapsed...they generally don't do that...and a report in the UK advises that the weight bearing capacities of our car parks needs to be substantially revised....most cars have become a lot heavier over the last 30 years...and all the new electric models weigh at least 30% more...often double or more...many current carparks were never designed to take this kind of weight when full.....scary stuff?...
