I read that wider tires are more sensitive to that condition.What you're feeling is called tramlining, and because the lotus is light and quick steering, its pretty noticeable.
Ask your doctor if Tramlining is right for you. Various side effects may occur, including 'feeling lightness' and the tendency to engage in social media posts often with sympathetically aligned individuals with similar afflictions. Stop Tramlining immediately if allergic to its occurrence.
