banning 10 year old cars is like letting these car sellers laughing there ass of to the bank. Anyway, my 2 cents would be 1) limit selling of new cars, 2) implement no garage no cars law 3) odd-even scheme on roads (Mon-Sat) 4) strict implementation of no stopping area 5) Control number of taxi units per operator 6) control jeepneys running on the road that causes major traffic!!
