Motion sensors might be set off by passing cars. Regardless, it is always better to turn off a light rather than leave it on - even for a few seconds.
Mythbusters proved that: http://mythbustersresults.com/episode69 Busted Myth: Temporarily leaving a light on is more energy efficient than turning it off and back on. "Through numerous tests, the MythBusters calculated that the power surge from turning on a light would only consume as much power as leaving it on for a fraction of a second (except for fluorescent tube lights; the startup consumed about 23 seconds worth of power). Furthermore, the wear and tear of turning the light on and off repeatedly did not reduce the bulb's total life expectancy enough to offset the increased electricity usage. Therefore, it is far more economical to turn a light off rather than leaving it on." Happy New Year everyone!
