Are you sure? That would be dangerous so I can’t imagine any keyless car ever doing that. Think about it, you start the car, go back indoors because you’ve forgotten something, inadvertently put the fob down, come out, jump in the car and drive off. All of a sudden the engine switches off and the doors lock, the steering lock engages in the fast lane of the dual carriageway? The fob being out of range only prevents the car from starting - otherwise there wouldn’t be so many keyless car thefts. I remember when I road tested my Evoque before buying it, one salesman pulled it out of the showroom and different one accompanied me on the test drive. As we pulled out of the dealership, a warning came on the dash 'key not found'. The salesman said not to worry, the keys were still in the showroom and as long as we didn’t switch off, it’d be okay.
