Companies like BYD and Tesla are positioned well for that if they can get their AV functionality proven out as both are fully integrated car manufacturers.
Waymo doesn't have in-house manufacturing and is, to my knowledge, purely software so they have lots of vendors along with a relatively low output of vehicles. Their 2025 and 2026 plan is to build 2,500 new cars per year. Each Waymo car currently costs over $100k. Even if Tesla was pushing out Model Ys as their robotaxi platform, they could flood the market very easily in both scale and price per mile _if_ UFSD (unsupervised FSD) was proven.
