The other thing that I have done in the past when driving on a two lane expressway and looking for something amusing to do is the following.
I wait for the inevitable "ricer" to appear weaving in and out of the traffic.
What I do is leave a gap between me and the car on the inside lane, sort of leaving the gate open for him. He comes up behind me goes to the inside lane and then and only then -
I SHUT THE GATE !!!
IT'S SO FUNNY the ricers are all over their lane looking daggers at me waving their hands giving me the fingers but
STUFF THEM just let them sit there for a couple of K's. Open the gate a little, just tempting them, and then shut it again. Jeez it's good fun. Once the novelty wears off I then let them go and they roar off down the road.
TRES AMUSEMENT!!!
