Ignoring it and just saying it needs to be fixed regardless is not exactly inaccurate, but it makes it harder to cause meaningful change because the issue isn’t understood as well. Either way it’s a problem, however being able to understand the scope of the problem helps find ways to actually combat it. This could be better than Uber and taxis, this could be significantly worse. However when looking at this rate, it’s not a useful statistic without knowing the base numbers. Obviously 4,000 out of the world is not the real number and it is much higher. It would not only be a small rate, but it would be near impossible to change it as the resources spent would have to scour the entire globe in reaching a small small percentage, meaning that it’s nearly impossible. If the rate was let’s say hypothetically 4,000 globally as the thought experiment the last commenter mentioned.

It’s very easy to say “oh it’s all bad and needs to be fixed” and a lot less easy to actually try and fix it. Nonetheless, understanding what numbers mean is a useful tool in quantifying the scope of a problem. I understand that this is a horrible issue, and of course measures should be taken to prevent it from ever occurring. After all they are customers of Lyft as well (Lyft is a two sided market / broker). * and I believe this is a rider number, one would want to see stats that include assaults on the drivers. * this is one moment in time - one would want trend data. * it assumes that all assaults are reported (they aren’t). We don’t have Lyft provided stats, but there are guesstimates () that report - precovid the average cost per ride was 25-26$Īnd we do have Lyfts revenue from ride-sharing.ĭividing by avg cost per ride, that gives us 138M rides in 2019.ġ.3 reported sexual assaults on riders for every 100,000 rides. Then again this is one of those companies that touts bullshit metrics like “adjusted EBITDA”, ie let’s make up a number that makes us look profitable.

I’m pretty sure they don’t want people to know between 2018 to today the number of rides went down. In their investor materials they don’t ever talk about the number of rides. To try and figure out the assaults per ride, It’s worth pointing out that the 4000 is an aggregated number from several years to 2019.
