&gt;Not so much. Drivers frequently run Uber and Lyft simultaneously. There is no &quot;stickiness&quot;.<p>I meant from the perspective of users and providers, not drivers (which are irrelevant in the case of self-driving cars...).  You have to get all these users to download another app when their existing one works fine.  That&#x27;s money that Tesla could be further investing in their core specialty rather.<p>&gt;You&#x27;d think so, wouldn&#x27;t you? But apparently that&#x27;s the direction Elon is going<p>Yes, which is why I&#x27;m asking; the fact that someone is in fact doing it doesn&#x27;t resolve this mystery.<p>&gt;I think its humorous this is thought of as expensive. How much does it cost to build an iOS&#x2F;Android app and run the infrastructure to match riders to drivers? $3-5&#x2F;million&#x2F;year? Tesla has hundreds of millions of dollars of credit available to it. And you know, the cars receiving software updates constantly.<p>Right, but they haven&#x27;t trodden the path of scaling up a ride-hailing app and made the numerous optimizations that Uber&#x2F;Lyft have made based on the unique problems of that domain.
