How would you use electronics to solve the 11' 8" bridge problem

Self-driving cars would probably screw up here as well.

The Tesla autonomous crash in 2016, where the semi trailer cut off the car and I think it drove underneath the trailer, not seeing it due to bright sky and white trailer or algorithm failure for above-vehicle obstacles.

Why don't we have driver assist technology? Some camera and stuff to alert drivers, before we go all out for autonomous cars?

If we need to look at this to stop people running a red light, then we should abandon motor vehicles altogether.  Alternatively, replace all traffic lights with roundabouts.


Seriously though, driver assist technology just encourages drivers to not be as aware of their environment as they should.  IMHO.

What happens then is that people fail to notice the roundabout and drive right over it.

On one memorable occasion two people drove over the top of a local roundabout from different directions at the same time and collided in the middle of it. The newspaper photo of the two wrecked cars perched on top of the roundabout was a truly WTF moment.

Pew pew!  Before the bridge have two towers on both sides of the road with a laser that goes across set to a bit below the bridge clearance (to account for vehicle shocks/bounce and snow on the road), if the beam is crossed it then activates a huge warning to stop.  I like the waterfall idea.  But that requires water/pipes, which will freeze in winter.  So could maybe use smoke instead?  It does not need to be a screen just something that grabs your attention like some kind of high pressure smoke jets from the top of the bridge or even shooting from the sides.    Not sure what is the best way to create this smoke though, and also keep it safe.  Needs to be a chemical you can just store and that it can activate at a moment's notice.

Best bet might just be a huge flashing warning, if you're still ignoring it then you deserve to ruin your car.  :P   Idealy there should be some solid metal beams right before the bridge that are slightly lower, so you hit that and not the bridge, if you still end up going through.  All these vehicles hitting that bridge are probably damaging it over time.

The water stop sign looks cool, but the down side is that when a driver sees this, the instinct is to slam on brakes.. on wet road...
Then the truck will slip and slide into the intersection anyways and crash into any number of things in the slippery water, maybe fishtailing around and hitting other cars. True, it would be a camera moment, but doesn't fix the problem.

Hmm, probably wouldn't work, but maybe a laser that paints a monster on the windshield with big teeth, like in the movie 'Alien'. I guess it would work if there was smoke in the area in front of the windshield. And then the message "In case you missed all of the other warning signs, your vehicle will crash into the bridge if you proceed."
