The dashcam footage, filmed on the A21 southbound near the North Farm junction, shows Will overtaking a slow-moving lorry, only to spot the pensioner calmly trundling along the inside lane on his little scooter.
The man, wearing a flat cap and jacket, appears completely unfazed as cars roar past him at full speed.
The unusual scene caused minor delays as concerned drivers slowed down to make sure the gent was safe, as reported by Need To Know.
Police have not yet released a statement about the incident, which took place on 27 October at around 1.45pm.
Under UK law, mobility scooters are banned from motorways, with users urged to stick to pavements or roads with lower speed limits.
