Here is a tip for all drivers.
If you drive a delivery van with your corporate logo on the side and company name on the vanity plate you should avoid this situation. When driving at close to 100 mph northbound on I-94 in Racine County, if a driver in front of you needs to suddenly change lanes at 70 mph due to a delivery truck pulling in front him and you need to lock up your brakes to avoid rear-ending him - it is not a good idea to yell at and make rude gestures to that other driver.
Especially if your office phone number is on the side of your van and the other driver has a cell phone in his car (what are the chances of that?).
I hope you find this advice to be helpful.
