Interesting read on the BMW 7 series Protection vehicle. Here's a tidbit from the field: I've heard, through the grapevine, about a team responsible for the safety of a certain high-profile individual (no names mentioned, of course ). About a year ago, they made a strategic shift away from BMWs as protection vehicles. Why? Because in emergency escape scenarios, it's crucial to be able to move the car even with the doors not fully closed / deliberately open. But with the BMW, if the doors aren't fully closed, the car won't budge. It's a fascinating look at how design features in luxury vehicles can intersect with real-world security needs in unexpected ways.
