Jumpol Rimsakorn, an advisor to the department, also revealed that to date about 20,000 have cancelled their rights.
He said that among the 130,000 who have reserved vehicles under the scheme, there is a possibility that some are waiting for delivery while others may have thrown away the booking.
He said that some made bookings at more than one dealer.
The department will send SMS to them, asking for confirmation if they still want to exercise the rights. This is to help the department estimate the exact cost of the scheme, he said.
