And are the only ones incentivized to, given the asymmetric danger between driving and walking. Drivers would be a lot more cautious with big spike in the middle of their steering wheel. Externalized risk (and unlikelihood of facing consequences if a driver were to maim or kill someone) has a very predictable outcome.

I think you misunderstand “Right of Way”. It’s not just an option for a pedestrian to cross, it’s incumbent on them to maintain predictable movement through the intersection.

Giving up Right of Way creates more confusion (think about the “go” / “no you go” game of a car not moving when it’s their turn at a 4-way stop).

I had forgotten about the rudder problems! Worth a read: https://imgur.com/a/5wcFx8M

> Perhaps the single most complex, insidious, and long-lasting mechanical problem in the history of commercial aviation was the mysterious rudder issue that plagued the Boeing 737 throughout the 1990s. Although it had long been rumoured to exist, the defect was suddenly thrust into the spotlight when United Airlines flight 585 crashed on approach to Colorado Springs on the third of March, 1991, killing all 25 people on board. The crash resulted in the longest investigation in NTSB history, years of arduous litigation, and a battle with Boeing over the safety of its most popular plane.

I can get used to the verbosity, but the archaic block editing copy/paste makes Powershell painful to use for anything more than the basics. Copying multiline text in Powershell first requires pasting it into an intermediary text editor and fixing up the new lines. And since the commands are so verbose, more often than not a command will span multiple lines.

That's fine if you can safely merge into the exit lane without slowing down traffic in the non-exit lane.

Here's when it's not OK: cars in the exit lane are traveling at 2mph. You drive up next to the line, slow down from 55mph to 2mph and wait with your blinker on for someone to let you in. Now you've slowed a second 55mph lane down to 2mph, blocking thru traffic and creating a dangerous stoppage in the non-exit lane.

Seriously, don't do this.
