Improvise adapt overcome

I highly doubt they're going all to the same place it would take way too long for say a bus or a train or whatever to drop these people off in each place that they need to go. Yes it would be more environmental if they all went in the same car or something but you know what sometimes we all have to go in a separate car.

Free up the roads so I can keep driving my muscle car that gets 10 mpg

Hmm on the surface it's seems pretty straight forward but any thought into this would rip apart the whole idea. This may work if you have plenty of public transport and have generalized areas for both work and housing/recreation. But at least in the US most cities have very little to no public transport. Commutes in our rather large rural areas can exceed an hour each way. No city in their right mind would allow a bus to travel 20 plus miles to pick up or drop off a single person let alone the 60 to 80 some people travel. You'd have to have separate transport just to get to a place where the public transport starts. At that point you might as well just keep using your own car. But hey don't take my word for it. Public schools barely meet their needs for kids who have to take the bus and the school levels start/finish at different times so buses can overlap schools. A single school has barely a fraction of the total population of an area. So sure lets just all dump our cars.

Average cost to public per mile: personal car- $1, 18 wheeler truck hauling goods-$18, bus-$5 to $11 million, light rail-$100 million. That is cost to build, purchase right of way, operating costs and maintenance not only of the transport unit but the road / rail as well. Oh... and that is DOLLARS PER MILE PER YEAR, EVERY YEAR. Ask a transportation engineer who doesn work for the company offering to design / build the rail project. Also note, all those people are crammed into ONE rail car; I breaks down... they ALL walk to work.
