No prob' ladies.

Another cool trick I read - not sure whether it was here or elsewhere - was : when you get in a situation where a driver has to consider you in planning his/her manoeuver (intersections in particular), downshift and spin your legs faster. If you're moving your legs at a slow pace, you look like you're going slowlier, if you spin faster, you look faster in their head. So they're more likely to wait. I haven't tested that in a rigorously scientific procedure though, your mileage may vary!

Another thing I do when I see a car coming in the other direction, preparing to turn left right in front of me, is think outloud a strict "NO" while looking at the driver. It's likely that most times they don't even see me, but it probably prevents me from slowing down/showing hesitation because I feel authoritative!!!

In all cases: keep your fingers well positioned over the brakes and think of an escape route at all times. Also works while in a paceline: if the car DOES turn/if the guy in front of me crashes/if that squirrel does cross the street instead of staying nicely put under his tree there, what do I do? I was riding in the middle of a paceline on a fairly high overpass the other day and thinking of my escape route if I went endo... quite creepy! but generally it's a good thing to think about it.
