I think this is an obvious case of someone attributing market-rate fluctuations to the only metric they can personally see with their own eyes: Their battery level. They can’t see Uber’s network of available drivers and other factors that influence the rate, so they overweight the only data point they can see.
This is similar to the phenomenon where people have a verbal discussion about a topic and then coincidentally see an ad for that product in an app later. When we see 10s or 100s of ads per day, it’s inevitable they we’ll randomly see an ad for something we’ve been discussing. Yet some people see these coincidences and wrongly conclude that their phones are listening to their every word, using AI to parse it out (without draining their battery), and then sending those keywords to an ad server for targeting. It has been debunked many times over but it’s still a commonly held belief that all of your phone apps are listening to your conversations.
It can be difficult to convince some people that coincidences are really just coincidences. Especially in this era where Big Tech has an incredible evil reputation in the journalism and media we consume.
