A problem with the floor selector in the hall is when some people enter the elevator together without selecting a floor. The system thinks that there is still space in the elevator, but in fact it is full, so it stops at different floors without anyone being able to enter. I've seen this happen quite often in a corporate building during the end of business hours and lunch hours.

At Twitter/X HQ they have these, and you can "trick" it into going express to your floor by pressing the button in the hall repeatedly so the car then thinks it is full and won't stop at other floors.
I've had the same experience, it's terrible.

Having said that, the default system is also ignorant to the current weigh of the elevator so it is still subject to stopping on floors without there being any space left.

Trying to figure out space available from the number of people seems unreliable, but I wonder if you can use a set of heuristics such as having a max weight at which point the elevator is assumed full and if it stops to let someone on but the weight doesn't increase assume the elevator is full (maybe require this to happen twice in a row?, IDK, false positives probably aren't too expensive.)
