Percentage of buses with interior and exterior facing cameraI just read that the Niagara Student Transportation Services has 25% of its school buses fitted with cameras. Not saying that applies here but for arguments sake, if we extrapolate that number to National Express, 20,000 x 25% = 5,000 school buses and if JamesWW is reasonably accurate at $6,000 per bus = $30 million hardware revenue to start....plus recurring service revenues....I like it........Comments?
