1) For maximum safety, you should assume that anyone behind the wheel of a car is a solipsistic, self-absorbed cocksucker with no regard for human life, and drive or walk accordingly.
2) If your phone drops a 911 call twice within two minutes, you should start to consider changing your provider and/or handset.
3) If your first instinct is to open fire on a vehicle that almost runs you down in the street, you should probably not attempt to obtain a concealed-carry permit or a firearm.
Just FYI.
