If you did any DD at all you would know that monthly maintenance fees are incluing in this and thus would carry on for years into the future. You made an excellent sales point..this equipment is good for years. Therefore they won't have to be looking for something new every year ... they just update what they have.
It was not FOLO, it does not mean FOLO dont exist. A FOLO is an advanced version of their GPS tracking unit equipped with the SDS system that detects the drowsiness of the driver.
PS: I dont care who developed the system if MCCY owns the right to produce it, sell it and make a profit out of it.
