The relentless pursuit of brutal gimmickry. Idk why they wouldn't content themselves with just making a really good car by putting this money and time into directly improving automotive technology. Unless their new business plan is to split the showroom between luxury sedans and neat toys for children. Free propeller beanie with every Lexus.
But I'm sure it'll work great whenever there's a continuous magnetic field under it. Ye canny change the laws of physics, cap'n.
