Birth of the ERP

[Published on 24 Aug, 1997]
The Land Transport Authority has begun to get all 670,000
or so vehicles here fitted with a hi-tech gadget for the
Electronic Road Pricing (ERP) system.
It sent out letters to the first batch of 50,000 motorists,
asking them to call any of 140 appointed centres for a date
to have the gadget installed.
If they keep to the scheduled period, they will not have to pay.
