Sometimes drivers need a little kick in the pants to keep them focused on the road — literally. GM's Safety Alert Seat does just that. The system, which sends subtle vibrations through the seat bottom cushion to alert the driver to potential road hazards, will be optional on the 2014 GMC Sierra.
The Safety Alert Seat works with other safety systems such as rear cross-traffic alert, lane departure warning and forward collision alert systems. For example, when the lane departure system detects lane wandering without a turn signal, it sends a pulse to the left or right side of the driver's seat.
GM says the new Sierra, which goes on sale this summer, has "available advanced active safety features never offered to full-size pickup truck owners." We first tested the Safety Alert Seat on the Cadillac SRX crossover; it's also available on the ATS sedan. According to GMC spokeswoman Kelly Wysocki, the Chevrolet Silverado will get the system as well; she couldn't comment on its availability in other GM vehicles, however.
