I looked into this last year, a significant part of the cost is in new hardware, both on the vehicles, but also sensors spread through the system. They all need commercial grade RF systems that allow for 2 way signaling communication and integration into the vehicles control systems.
- bobthepanda 2y agoalso they need to be rated for the operating environment. you can't stick any random part from newegg in there. Tesla used non-automotive grade touchscreens in some cars and so they died early: https://www.thedrive.com/tech/27989/teslas-screen-saga-shows-why-automotive-grade-matters https://www.thedrive.com/tech/27989/teslas-screen-saga-shows... Automotive grade has very high requirements: > Grade 0: High Temperature Operating Life (HTOL): +175C for 408 hours. High Temperature Storage Life (HTSL): +175C for 1,000 hours. Temperature Cycling: -65C tp +175C for 500 cycles And generally speaking transit agencies aspire to buy higher-reliability, longer-lasting equipment than your average consumer car.
- krallja 2y agoI’ve noticed that my car’s touchscreen operates at a very high temperature at all times - almost hot enough to burn skin, which seems like a weird choice for something designed to be touched by skin.

- bobthepanda 2y agoThat probably means that whatever is running behind the touchscreen is the thing that’s hot, and the touchscreen is doing a poor job insulating that heat. But is also illustrative of why the automotive standards are the way they are.
