I do not think this in entirely true. In many developing countries, 
motorisation is a very new trend and most of the cars have been purchased 
in last 8 to 10 years ( this is true for india). Therefreo, the share of 
old cars is relatively low. For example, only 10 to 15% of car fleet is 
Delhi is pre 1981 fleet. 
What may be true is that the technology used for the cars are old and the 
emissions are high

Vehicle ownership if you take both cars + MC/SC, then for some urban 
areas, the vehicle ownership is quite high ( e.g., delhi - more than one 
vehicle ver household)

We have this info for Delhi.  I will pull out some of these numbers. In 
Delhi trips on public transport are 62%. Vehicle ownership as I said one 
per household including SC+MC.
