If you are looking for a product that keeps you safe while in your car this In-Vehicle Blind Spot Detection System is sure to help. "In the presence of any approaching vehicle these high intensity pulsed beams get reflected back to the vehicle and is detected by Infrared sensor TSOP 1738.Whereas in the absence of any approaching vehicle no reflected Infrared beam is present and output of TSOP infrared sensor is High. It should be noted that output of TSOP sensor is high when no infrared beam is present and become low in the presence of pulsed (36 KHz) Infrared beam. Thus Software continuously monitors the output of both TSOP sensors and generate alert if there is change in the output of any TSOP sensor. User has option to choice alert on LCD only or user can go for voice alert too." Thanks Garry.

I never got why cars don’t have this already. Must not be reliable enough?

Volvos do, called BLIS, the Blind Spot Information System. Albeit more advanced than an IR sensor, it uses cameras under each mirror to look for the presence of anything vehicle and motorcycle shaped.

Now that could actually be useful. Especially if you are really lazy. I still want one!
