Jeez, it's a k'nightmare! You know the scenario: we're flying along, taking up the whole inside lane while a car is queezing past on the right. Then, suddenly everyone yells, "car up, car up", obviously beacuse of a parked car, so we all fly into the right lane while this car is trying to get by...........YIKES.

Being old and sensible, all I can think is: "hmmm, imagine if a car door opened right now."
