Bigger is not always best,if you're confronted with a BMW X5 , it's quite a challenge to get out of a parking space or passing on a street with parked cars down both sides, risking damage to said vehicles, making room!
Will the BOE get in there before it's announced? Oh the unit of 10 seems to be applicable now it seems as a measure!
So that's 3 changes of scale up to now in my lifetime!
