I certainly hope that there's no future for the SUV or van, except for people who really need them.
Quite often at the gym or supermarket I find myself parked between two vans or SUVs. Because of their size, I cannot see well enough to back out safely. Also, if I am making a left turn from the left turn only lane and an oncoming van or SUV is also making a left turn, I cannot see around it well enough to tell whether it is safe to proceed. They increase the danger faced by other road users.
I'm glad that you allow that some people have a legitimate, often commercial need for such vehicles, along with pickup trucks. Also for towing purposes, something I did for many years. I can't imagine the micro car pictured above towing anything larger than a Radio Flyer toy wagon.
But I agree with the difficulty you cite in backing out of a parking space when you're boxed in by these monsters. I suppose as more cars come equipped with rearview cameras and proximity sensors it will get better.
Yet like me I know you remember a time when roads had cars of all about the same height. And with clear windows, not all tinted dark. In lines of traffic you could look right through the windows of maybe 5 cars in front of you. Nowadays my line of sight is limited to a solid wall of metal and blacked-out glass right in front of my hood. And if you drive one of these smaller cars you're even more in a hole with the surrounding traffic.
