He reckoned on the trend by cycle manufacturers to build the bottom
bracket higher off the ground these days

What happens if/when the brakes fail? You can't stick your feet on the
ground.

both brakes failing at the same time? you either don't bother
maintaining you bike properly with two working brakes, or you're so
unlucky you probably don't have much longer to live anyway.

What happens if the brakes fail on your car? You can't stick your feet on
the ground. If you've maintained your brakes properly, it won't happen.

With a higher saddle you can still stick your feet on the ground. You just
can't do it when your posterior is on the saddle

Sit on the frame and put your feet down.
Jam your foot against the back tyre.
Put a little more effort into maintaining your bike.
Learn how to fly.

One of the funniest things I ever saw, which involved bringing a bike
to a quick stop, was when one of the school bullies whizzed down the
road, and aimed a kick at the seat of the pants of a boy on the edge
of the payment.

He connected satisfactorily, but the recoil, and the fact that he was
travelling at speed, meant that his foot ended up between the spokes
of his rear wheel which, once they came into contact with the rear
spokes, brought his rear wheel to a complete standstill in an instant.

Not sure I would recommend that though, as he screamed in a huge
amount of pain. hehehe.
