If this is not already a known secret that LTA will eventually goes for GPS but just that they still cannot solve some technical issues. (Understand system still on trial). LTA definitely is aware the current COE system is being manipulated by car dealers when they allow 3rd parties to bid, but the government need to support business and these business employ people (my guess only), so they are still looking for a win-win solution. Win-win means business still goes on while LTA continue to get high COE, haha
Personally, the only 'solution' is improvement to public transport system. Our traffic lights, bus lane, gentries, bus stops, bus routes, etc need a complete overhaul. You just can't leave them status quo and expect things to run. People sitting up there just warm their seats and talk only no actions. Make them take the public transport to understand. Our minister took the train for a couple days and gave up right?
