single drivers and drivers with passengers (not necessarily with a wife) - in some cases, this is a big difference.
There are dedicated lanes for cars with passengers - HOV lanes, where there is a lower chance of getting stuck in traffic.
Also, families with children may be allowed to drive on dedicated lanes for public transport, and of course, there is a lower chance of getting stuck in traffic.
