Well, here I am in 2020 finding out that safety engineers in London are a bunch of morons.<br><br>Seriously, do trucks in Europe not have air brakes? There's a reason a loud, annoying unnatural sound is used in reverse alarms and it's not to "make the neighborhood quieter." It's to tell people that HEY PAY ATTENTION THERE'S A BIG HONKIN' PILE OF METAL AND RUBBER ABOUT TO SQUASH YOU LIKE A BUG.
