Talk about everything having lasers! These lasers are for your garage, to help you park, of course — at least they get some cool points for looking like turrets from a B-movie spaceship. The motion detector spots you pulling into the garage, and this little unit zaps your car with a point of laser light to let you know whether you’ve pulled in sideways, again.
Seriously, will this ever stop? A brick on the floor for a tire to hit or a cork hanging by a string from the ceiling work just fine and are practically free. Amazon has this marvel of modern marketing priced at $22 and change. What this thing really needs now is an array of LEDs so you can feel like you’re in Close Encounters of the Third Kind.
Couldn’t help myself, I had to take a look for pocket knives with lasers — check it out.
