If you have all the cars driving themselves they can function more like a swarm/grid of vehicles managed externally vs individual agents working against each other. This means you can have cars going like 80-100 mph but driving bumper to bumper.
- jliptzin 7y agoWe will have flying cars long before that happens
- beojan 7y agoYou mean like a train? Why not have trains instead?
- lallysingh 7y agoStops.
- beerandt 7y agoRails are expensive and limiting.
- smachiz 7y agoBecause trains can't take exits... unless the whole train wants to.
- naavis 7y agoAll cars are not going to the same place.
- standyro 7y agoI love trains but for some stupid reason >$200 million per mile is the average cost for urban rail. We already sank a huge upfront investment into the interstate highway system, so we'll have to settle for a private enterprise solution with semi-autonomous vehicles. At least, until the US Congress becomes less dysfunctional...
- dopylitty 7y agoThere’s no evidence that this sort of system is possible given the latency of wireless communications and probability of momentary glitches in real time systems long enough to cause a cascading set of failure leading to crashes.
- merpnderp 7y agoWell, maybe. We’ll likely never have cars zippering through intersections at high speed, but we could likely increase intersection throughout by mind boggling amounts while still allowing for multiple systems failures not killing anyone. Say the power cuts in a car, or worse its location updates no longer match the surrounding cars’ sensors, the cars in its mesh could immediately alert all the cars around that it is no longer updating its location and might be anywhere, so all cars in the area should go into low speed safe mode. It should be a doable to some degree.
- millettjon 7y agoIt's not that different from thousands of human drivers coordinating using waze during rush hour.
- lavezzi 7y agoI think bumper to bumper is a but much, you still need enough distance between cars to compensate for unexpected events.
- avar 7y agoYou don't need them to be networked to get large benefits from computer controlled, and doing so adds a lot of complexity. At 60 mph the stopping distance including reaction time is typically referred to as around 80 meters[1], and that includes 20 meters of reaction time. In modern cars like Teslas it's more like 40 meters[2], but 20 meters of that 80 (or 40) is human reaction time. If you can cut that down due to much faster computer reaction times you can get a lot more road throughput, of course a logical step after that is to consider networking the computer control, but talking about that from the get-go seems to me to be needlessly jumping several steps ahead. 1. https://www.brake.org.uk/facts-resources/15-facts/1255-speed https://www.brake.org.uk/facts-resources/15-facts/1255-speed 2. https://www.theverge.com/2018/5/30/17409782/consumer-reports-tesla-model-3 https://www.theverge.com/2018/5/30/17409782/consumer-reports...
