The problem I see with this is latency. Round trip time for a laptop on wifi (this will need a wireless connection to the vehicle) could get up to 200ms at times. At 60mph the car will be 17 feet from where the operator's screen shows it best case. You've also added 1/5 second to all reaction times. A lot of people would die if every driver's reaction time went up by that much.
- DigitalJack 10y agoA driver's reaction time is already 1000 ms as is. Latency is an issue, but I think 200ms is a pretty high number. you can get 250ms round trip to a geosynchronous satellite. Surely we can beat that on the ground.
- pilom 10y agoWell, round trip time of light to GEO is 280ms plus processing time on the satellite plus "last mile" connections on earth. I usually see closer to 500ms on satellite internet. In most of Canada, I've never seen a wifi network give me better than 150ms to AWS in us-east in Virginia or us-west in Oregon. Even in SF pinging another server in SF with a wifi connection in the middle can get more than 80ms. For a bus system in a constrained area, you may be able to do it, but you'd probably be better off just going with tracks of some kind to eliminate drivers entirely.
- ryanmarsh 10y agoSome are suggesting that 5G adoption will enable services that will need compute to be near the cell tower, or the backhaul. Services such as low latency AI based assistants and autonomous vehicles. Sorry I can't find the articles I've read on this.
