If you're solution to the problem is to not solve it under the constraints offered, then you're not really solving it. Someone could easily use your argument to say we shouldn't have self driving cars in the US either when we can just use automated trains.

That is of course, unless, you DO solve it under other constraints. Sure, you haven't solved X problem with Y solution, but you've still solved X problem. Self driving cars may not be the solution to ALL kinds of traffic problems, but it turns out, they don't have to be.
