No English article yet, but here’s a video from last time around, when it was presumably already the oldest street-approved car there was.

In the UK, vehicles first registered more than 40 years ago and not substantially altered since then, are exempt from annual testing (and Vehicle Tax - VED). The reason is that no vehicle of that age is capable of passing the current test. There is also the assumption that cars this old are almost certainly well-looked after.
The London Steam Carriage was built by Richard Trevithick in 1803 and it is considered to be the first self-propelled passenger-carrying vehicle. Although Cugnot’s steam powered vehicle predates Trevithick’s, Cugnot’s car was designed to haul artillery, not passengers.
Trevithick had built his first experimental steam carriage in 1801, which was nicknamed the “Puffing Devil”, and drove it up a hill in Camborne, Cornwall.
Trevithick drove the 1803 steam carriage through London for about 10 miles at a speed of 4 – 9 miles per hour (6.4 – 14.5 km/h). Unfortunately, the vehicle was immediately destroyed in a fire, but the original drawings that were submitted with the patent have survived.
