A quick response from the Seneschal:
Subject is known BB. Apprehend if at all possible. Will attempt to find you assistance. What is your location/direction/destination?
Michael sees that the bike behind them has jumped up a vehicle in the queue, while Lars' bike has begun to slow.
Answering the location/direction question is going to require a Wits + Streetwise roll. The more sux you get, the quicker help will be able to find you. Michael is trying to remember an escape route from the bikes along your current path. That's Int + Streetwise; sux means you can plan one along your current route, the more sux you get, the sooner you'll find it. If you fail, I'll call for a Wits + Street -5 (distracted by driving) roll at some random point coming up. Turning off quickly to avoid pursuit will be a Dex+Drive roll.
