So here's my comparison between cars, boats, and aircraft:
Car Boat Air
Worst case you can safely stop Sometimes Yes No
Reaction time required 100ms Minute Minute
Trajectory tolerance 0.5m (city) 5m (harbor) 5m (takeoff / landing)
Trajectory tolerance 2m (highway) 100m(open sea) 1km(mid flight)
Collision survivable Yes Yes No
Please add or point out my mistakes (I kinda pulled the numbers out of my ass).
- elif 5y agoI don't think you've ridden many boats in Amsterdam canals if you believe they can always safely stop and have a minute reaction window.
- fullstop 5y agoI'd disagree with the boat being able to safely stop, especially the massive ones.
- im3w1l 5y agoI'm not saying they can come to an instant stop. But if they do stop they are in not in danger to themselves or the surrounding traffic. That means that if you see a sticky situation about to happen then you can start slowing down to make everything easier and you can keep slowing down until you are either able to safely handle it or completely still. If the computer has no idea whats going on then slowing down and requesting human assistance is very viable.
- nradov 5y agoStopping in heavy weather or currents is not at all safe. The ocean is a dynamic environment. Vessels must maintain steerageway or else they risk broaching or drifting into obstacles. In shallow waters a vessel in distress can sometimes drop anchor to hold position but that isn't always a practical option.
