Last time the Sharif brothers started the Yellow can scheme, there was a lot of loot and plunder with a lot of the funds going into their own bank accounts.
On top of that, a lot of the cars were "sold" to government servants, ministers and their families and "friends" of influential people.
This will probably be yet another scam.
Instead of scams like these, they should invest in schools and businesses so people can upgrade their education and find jobs.
Driving cabs around on already-congested roads is not a source of worthy employment.
