"Safely" will never mean a 0% crash rate. So, when a failure occurs that causes the vehicle to crash uncontrollably the property damage and casualty level will be determined largely by the vertical density of the vehicles.

Two issues with this:
a) the cost difference between container ships and trucks is not so large as that of air and ground travel
b) the reason that less efficient trucks are used is exactly because there's an economic demand for delivery and it is the price/time optimal solution.
For someone with a commute that can be shortened from 90 minutes to 15 minutes and makes in excess of $250K a year this is a solution. For everyone else it doesn't make sense.
- jessriedel 10y agoThe arguments you're making are no more convincing than historical ones like "it will never make economic sense for an individual to pay for their own computer" or "elevators are an inherently dangerous form of travel".
