If the system detects drivers are distracted or daydreaming, it would then attempt to get the driver’s attention by vibrating the steering wheel or pedals. Vibrating driver controls like the steering wheel and pedals is something that Jaguar also wants to use in an attempt to avoid saturating the driver with flashes or audio signals. If a driver exceeds the speed limit, an actuator at the top of the accelerator pedal arm will create a warning that the driver needs to hit the brakes and slow down.
