Does anybody know what will happen if you enter the toll-road and go through a gantry, then take the next off-ramp before the next gantry and go the backroads. If you rejoin the freeway further down the freeway, will it automatically assume that you exited, or that there was a problem with your e-tag? And how could they prove their case without manually going through the cameras? There exists an opportunity here to query each and every charge that you receive, to their detriment...
