Why should a user care about an extra MB’s on their phone for a frequently? If we were talking about 10 year ago storage prices/capacity or much larger apps sure this would be a discussion but it shouldn’t be nowadays. I get it programmers like to focus on efficiency, but I promise you 99% of users don’t care about the extra MBs with the price of storage and value of Uber nowadays.
A whole lot of Ubers big spenders. On a individual basis, but I know many consultants/sales people traveling all over the world that spend hundreds or thousands on ubers a month and want the ease of use. Those are Ubers profitable customers buying lux/black cars etc. in addition to many wealth families that use Uber all over the world in vacation. They should be solving for those customers over a customer worried about an extra 50 or 100mb even on their phone
