Faster, cheaper (than car) and with less emission right? Seems quite good to me.

It seems an awful solution compared to the worst underground line. Modern lines, as I said, can transport more passengers than they move per day in a mere minute... If you add the time to make 3.6 miles probably they will complete the journey in 10-15 minutes.

Yes, but full scale metro lines are very expensive and not every situation justifies that kind of spending.

If this system can be built more quickly and at much lower cost than traditional transit systems, then it could well be very successful.
