One car every 2 seconds sounds totally plausible. In fact, that number actually seems pretty low to me. A single lane/tunnel should be able to handle automated cars traveling at a 2-second following distance no problem, so that just leaves loading/unloading as a potential bottleneck. How many on-ramps do you think it would take to reach a capacity of 0.5 cars/second? I'm really curious as to what sort of problems you're envisioning which would make that "impossible".
- liability 6y agoHow many amusement parks can load a ride car once every two seconds? Even continuously moving ski lifts aren't anywhere close to that and that's basically ideal conditions where the seat is delivered straight to your butt, and most users can reasonable be expected to be fit and coordinated. In the real world, people dawdle. You'd probably need dozens of loading lanes to reach .5/s, which means the stations are very large and expensive caverns.

- sudosysgen 6y agoYou need people to drive their cars safely into the intake with an average delay of two seconds, to match a very middling subway system running at a delay of 7 minutes instead of 2, assuming that every single car is filled to the brim. This is completely ridiculous. You won't be able to make people do anything with an average delay of 2 seconds, without any mistakes. The question isn't on-ramps, it's getting people to merge or arrive at the dispatch on average every two seconds without making any mistakes.
- Ajedi32 6y agoAh, I see the misunderstanding here. Nobody will be driving in these tunnels. Only fully autonomous cars running approved software will be allowed in. Those sort of problems go from "impossible" to "almost trivial" when the exact movements of every vehicle in the tunnels is being monitored and controlled by a centralized system.
- sudosysgen 6y agoThey still need to get somewhere in order to enter the system, unless you're banking into full self driving. And they need to get there at a pace of one car every two seconds, or there needs to be a buffer.
