Hi All Had a littlt of a tête-à-tête with a driver today. I’ll try and keep it short. Urban narrow dual carriageway - 2 lanes in each direction (A316 between Richmond circus & the Kew “gasworks roundabout” heading towards central London for those who know it). Riding justifiably in primary – around 20mph (30mph limit) traffic flow fairly light – everyone able to overtake me – part of regular commute etc. Get a close overtake on purpose with driver swearing through passenger window – something about should be on the pavement – you know the routine. Lights red just ahead so I easily caught up with him – on driver side now – he’s still ranting and swearing – threatened to “f…ing knock you off next time you’re in the middle of the road…” etc – I’m sure we’ve all met them – lovely chap – I for once kept my cool and tried to reason with him but as lights changed he carried on ranting and swearing and accelerated off. My question is – while he was threatening to “knock me off…” I was well within reach of his ignition. A quick lean through the open window and his keys would have been mine. Having had this situation twice in the past, If I simply leaned into the car and removed the keys (with full intention to return them via the police) could I end up being charged for taking his keys – my defence would be that he was threatening me with an offensive weapon (his car) and I was using justifiable force to disarming him – but I get the feeling that with no witnesses I’d somehow end up charged. Any thoughts?
