Hi Andy,Yes I did chuckle at the 4D naminghttps://tfl.gov.uk/info-for/media/press-releases/2026/march/tfl-launches-trial-of-new-radar-based-speed-camerasApparently its due to the radar being 4D and doing elevation alongside distance, speed and angle - not sure I'd agree with either the 3D or 4D naming for radars that but there you go there's the 4th D!Strange thing for TFL to be trialling but it is what it is I suppose.
