You can easily say that the majority of people do not even use WEP, and that their wireless networks are extremely vulnerable and open to attackers. I simply drove around with a laptop on the passenger's seat, running NetStumbler, and it picked up around 40 signals, and only 5-7 of them were secure. Some folks actually named their network the same as their street address, actually making someone not need a GPRS. Also, it picked up a signal driving at 60 MPH in an interstate.
