Brad Templeton has good article on the big Cruise stall:
www.forbes.com
He offers a few solutions:
1) Have the cars use more than 1 data connection so that if one fails, there is a back-up.
2) Cars could use a spare TV broadcast channel to communicate with remote assistance.
3) Have cars communicate with each other in a mesh.
4) Get the autonomous driving better at handling these cases without remote assistance
His conclusion:
GM’s Cruise Falls Down During Concert Cell Overload; Here’s How To Fix It
GM’s Cruise robotaxi unit, hot on the heels of receiving its permit to charge for rides all day in San Francisco, did not have a good weekend.

Here's some additional local San Francisco news related to commercial auto autonomy:
missionlocal.org
In the commentary, there was an interesting reference about having the possibility
of first responder overrides, similar to firefighters having keyless overrides (by law)
for elevators...
They also quipped about the booing of Waymo during a Patti Smith concert.
As it happened, I was at the Stern Grove event too, joining in the boos, mainly reflecting
the youthful protest energy just for oldtimes sake.
Because of safety alone, I'm warming up to Waymo here in town, although
I remain concerned about congestion disintermediating public transportation.
Would their business model fail with congestion pricing?
At least folks are starting to realize that safety as the #1 factor is finally ruling
the day. It may be that Tesla has missed the market opportunity to the pioneers
at least in SF.
Driverless cars won the day. What comes next? Plugging them in — and fighting.
The spectacles of a driverless car placing itself between firefighters and a burning car, another blockading fire rigs on a narrow San Francisco street, Driverless car companies were last week granted full and unfettered access to San Francisco. What comes next? Fighting.

It seems that Cruise is not actually stopping for pedestrians but rather passing them at a distance the Cruise thinks is "safe". Cruise really should stop and yield. That is the law.

Here we see another example of Cruise not stopping for pedestrians crossing the street and just maneuvering around them at close range. You can see the pedestrians look back at the Cruise like "WTF".

Since we don't get to see the visualizations on Cruise like we do with Tesla, we don't know if this was a perception issue or a coding issue - did it properly see the pedestrians and their distance from the car? If so, the coding was at fault. If it did not, then the sensors were not working properly.

True, we don't know for sure. But the conditions were normal and I don't see any reason why the sensors would not have detected them. So I am assuming the perception did properly detect the pedestrians and their distance from the car. So my guess is that it is a planning issue but I think it is deliberate. I think the Cruise is programmed to be that assertive since we've seen this behavior consistently from Cruise for awhile now. In fact, it is possible that Cruise deliberately programmed the cars to be assertive with pedestrians because of the issues before where pedestrians would jump in front of the Cruise to cause them to stall. And since the cars have excellent perception and good path prediction of pedestrians, Cruise probably feels like the cars can confidently get that close to pedestrians and not hit them. I get that you don't want AVs to be overly cautious to the point of paralysis but I don't like this behavior from Cruise. I think it is too aggressive. I know I would be freaked out if a driverless car just drove right at me like that. I think AVs do need to yield to pedestrians.
Depending on locality it is likely illegal behavior. I'm pretty sure that in Oregon you are required to stop, and stay stopped, until the pedestrians have cleared the next lane past the one you are traveling in. (Which for a two lane road would mean that they completed their crossing.)

finally we can all agree on something other than Krispy Creme donuts being great
I’ve noticed they’re a little too impatient lately. Seeing similar behavior at stop signs where it will start rolling well before the intersection is clear of pedestrians, even if it hasn’t waited longer than a reasonable amount of time and there is plenty of space to go after the pedestrians crossed. Also they will pose fairly aggressively for unprotected lefts (e.g. both at an angle and with the wheels turned), even rolling towards the intersection with oncoming cars sometimes. Feels a bit too far on the wrong side of assertive IMO
I'm going to play contrarian and say it's not illegal in California. California law only requires yielding to pedestrians. It does not require the car to wait until the pedestrian is fully crossed nor does it have other similar more narrow requirements (like clearing the next lane over), nor does it require the car to come to a complete stop in front of the pedestrian (other than the separate requirement due to stop sign, which the Cruise did stop for already).
Do California drivers have to wait for pedestrians to cross the entire street?
Relevant section of law as it relates to drivers:
Law section
A similar idea applies to cars crossing a stop sign intersection. You are free to start moving as soon as the car with right of way does, and swerve around and pass behind them. You are not required to wait until their car has fully crossed the intersection before you move from your stop.
So while the car was very aggressive (and scary for pedestrians, given there is no way to have "eye contact" to establish the car is aware of the need to yield), what it did was not illegal.

Is Cruise experiencing more difficulties since they were approved by CPUC? Or are people watching and scrutinizing their driving more after the approval?

Since the CPUC permit, Cruise is adding more riders and more miles will mean statistically more chance of experiencing an issue. But part of it could be coincidence too. For example, the festival with the cell signal outage just happened to occur the day after the CPUC vote. Also, I do think Cruise is facing much more scrutiny because the people who are against the CPUC permit are on the lookout for anything they can use against Cruise.
Hate to break it to you but Krispy Cremes are nasty they taste like raw dough...
