Look out below, err in front!

Even if you’re not drowsy, any form of distracted driving can lead an accident on the road. This is why more cars are featuring collision alert systems that warn you of an impending crash. Ford vehicles follow a similar formula to Volvo’s when it comes to monitoring the environment around the car. However, instead of cameras, Ford uses radar sensors.

Outfitted to cars with adaptive cruise control, the radar sensors can detect if a car in front of you has stopped moving. If you continue to drive towards the stopped vehicle, an audible warning and red-LED light will flash on the windshield. The alarm is meant to catch your attention in time to spot and react to the hazard ahead. In addition to this warning, Ford pre-charges the brakes to allow for quicker and more aggressive speed reduction, ensuring you don’t rear-end the car in front of you.

A flashing red light on your windshield and a loud beeping alert is a pretty embarrassing thing to explain to your passengers. Wouldn’t it be better if these systems were a bit more subtle? Cadillac offers such a solution, that doesn’t alert every one of the driver’s absent-mindedness.

The lane departure and front collision warning systems in Cadillac’s just vibrates the driver seat, so only the person behind the wheel is prodded by the alert system. Directionally-specific vibrations buzz in the corresponding direction to warn of potential danger and which direction it lies in.
