That looks pretty Kuuuul.... but can you imagine, evan if they worked flawlessly and never failed in flight....
but if there was 10,000 of them flying around cities every day.... all fighting for landing places
People don't obey road rules now, how many would obey 'air rules'?
There would be these things crashing into each other everywhere.... bits of aircraft and bodies falling on the ground everywhere....
Look at road rage these days? Imagine if there was 'air rage' as well?
There are some folk who shouldn't be driving
.... imagine if they were flying those things?
