Im same with handbrake since my mid twenties. To be fair with good reason, after hitching up at Tesco Harlow only to turn around and see the whole kit and caboodle rolling across the yard with me on the catwalk! Got away with it though, no one around, nothing was hit
If youre on a ferry when in freight drivers lounge mention that you can’t remember putting your handbrake on, you’ll be met with a sea of suddenly concerned faces and at least one at reception asking to go back down to check!
