After the Belgium GP at Spa, I was trying to help a neighbour in the campsite start their BMW; I had a little bit of an ulterior motive, as they had a jump-start pack, and we'd flattened the battery on Jude's X-Trail over the weekend too. The BMW sucked all the juice out of the jump start pack, and still wouldn't go, so the guys were pushing. I gave them a hand. We were pushing backwards out of the parking spot, doors open pushing on the pillars. I was pushing on the passenger side. with R hand against windscreen & 'A' pillar.
