I had such a device on my company provided vehicle. I found my self driving to please the device instead of being aware of driving conditions. I feel it made me a less safe driver. The technology was problematic resulting in false alerts also. Shortly after I retired tracking equipment was installed to locate one's position-presumable to facilitate more efficient use of personal. Had a major effect on moral. It was the company's vehicle and they could do what they wished so the price for free transportation.
