So, how is restricting would be Taxi drivers from driving a normal car help wheelchair users. Is there data available that shows us the optimal number of wheel chair accesible taxis? Maybe that 40% drop was warranted?
Uber had this covered as well by the way.
If you can't see how making new entrants buy a wheelchair accessible vehicle over a normal vehicle would help wheelchair users then I don't know how to explain it any clearer.
I doubt the NTA would have introduced the restriction or the grant aid to help people buy wheelchair accessible vehicles if they didn't have data to support their policy.
