for driveways its hard to beat a run-over air tube for reliability, they are not all that aesthetically pleasing or discrete; but even bikes will set em off and short of a branch falling on one they wont false.
its a vehicle sensor, not a person detector.. if staked down at a choke point nobody should be able to drive around it.. and even if they on a plastic bike the'll set it off.
if you need to be alerted to people on foot, then get a bigger driveway so nobody will be willing to walk it or i dunno, use the appropriate sensor.
