The problem with the new area in Central is that GPS doesn't work in the garage.
If they wanted a REAL solution, they should have put this rideshare area near/across from the MBTA blue line stop, and encourage people to take the Massport shuttle there. Then, when people see the huge mess, they're more inclined to take either the blue or silver lines (SL3 serves the blue line airport station and goes to South Station)
