Not to mention the extra options for car parking spaces, there are more benefits to carpooling. Schemes can be both informal and formal. Informal schemes can get people to ask friends/colleagues at work to lift share. Employers can also get involved by getting people together to see if people live near each other as in big companies, it might not be possible to ask each individual whether they want to car share. More formal approaches are with schemes that work across the country like LiftShare and FreeWheelers
