Contributor "Q"posts in this scene from Ikea, a 4x4 with horse box having to use four spaces. As Citizen Q points out: this leaves some lovely bike parking
When you consider how much a horse box + horse weighs, this is actually a valid use for a vehicle with bigger engines and all wheel drive. What is surprising is taking a horse to ikea. Having taken a small child round the shop -indeed, having had a small child run off in that shop- it is clear that taking a small child round is a pretty stressful experience. But doing it with a horse? That is bold!
