Less dangerous than it might be
This would be the same clear thinking local authority that painted a big M'WAY on one of the lanes of a major roundabout so that drivers would know how to get to the Medway Towns (for clarity, the roundabout is on the A2 midway between Rainham and Gillingham - so already within the Medway Towns).
Unfortunately, the previous exit led to the M2. Guess how many last minute panic turns were made by drivers heading for the motorway . And how many accidents they caused.
