Why bother? If it happened once it will happen again. You might as well throw a tissue at the sky in an attempt to stop the rain. They just don’t have any reason to care who picks you up so long as they get your money.
If its reported multiple times they can take action. If not, well, its like voting. If you dont, you are supporting whatever the system is in the end. And they care because if there are safety issues it will hit the bottom line eventually.
Of course they have a reason to care -- the worse quality customers receive, the more they'll defect to a competing service with higher quality.
All of capitalism is based on companies competing for customers by providing better products. The entire reason Uber exists is to provide a better product that taxis or Lyft. They have every reason to care, and there are tons of cases of drivers being banned from Uber because of repeated complaints. I believe your pessimism here is totally unfounded.

Not true at all. Lyft and uber are virtually identical; there is no consumer choice. Companies have an incentive only to provide a product that is not worse than their competitor, but the market is still anti-labor and anti-consumer.
