the OBU is stupid. I don't need to know that the accident is on lane 1 and before the Stevens Rd exit after i'm already at PIE Toa Payoh area, its toooo late.
I NEED to know that information before I get into the PIE i.e. before all the entrance point into the PIE be it at Tampines or at Bedok.
I think the present system picks up where you are along the expressway and then gives you the information. They should blast the information before I get on the PIE so that I can decide not to use the PIE
