City planners are aware that continuous driving is enjoyable and go out of their way to eliminate that enjoyment wherever possible. It's called "traffic calming," though I'd argue the results are the exact opposite of calming. Drivers who are comfortable, having fun, and moving continuously are much more likely to speed and get in accidents than drivers who are annoyed and constantly vigilant for conditions changing second-to-second (like stop-and-go traffic).
