1. Place tax on Gasoline, increasing its price 50 - 100%. Then use the tax to develop additional road infrastructure.
2. Allow the issuance of Driver's License only to those who have stayed in the country for at least one year.
3. Similar to Family Visa, institute a minimum salary requirement (maybe at 3000 or 4000) when applying for driver's license.
4. Move industrial facilities way farther, like in Al Khor or Al Mesaieed (including the ports). Promote / push other companies to other cities / areas of Qatar. This will allow decongestion (where people will live near their work) while allowing focus to Develop Qatar as a pure commercial / tourism area.
