The thing that made it so notable at the time is that it was basically using 'all the things'... a hardcoded password by Siemens, a zero day in some Siemens code, a couple stolen private keys from Taiwanese hardware manufacturers, and 4 Windows zero days (the print spooler one, something with Shortcuts, and two escalation of privilege vulns).

This is a feature, not a bug. With the setup of "two 1 way streets feed into a scramble", crossing safely on a "do not walk" is trivial, with only a single direction to look for many of the most common crossings.
A solution that solves the noise problem without returning to beg buttons, is to make the intersection a flashing red at night. It becomes a 4 way stop where pedestrians have the right of way. Everyone wins.
Uber, by comparison:
'Trips during the quarter grew 21% YoY to 2.8 billion, or approximately 30 million trips per day on average.'
That would be about 350 payments per second if load was evenly distributed.
