Well at least Frank won't feel so lonely now......
Remember that the Roadster clearance is 3.25inches.
Obviously gate stops are a menace to watch out for.
A quick Google tells me:
There is no minimum ground clearance for road vehicles (laden or unladen). This is not included in either The Road Vehicles (Construction and Use) Regulations 1986 or the more recent EC Car Masses and Dimensions Directive EC 95/48.
There is a maximum height specified for speed humps. The approach angle should not be more than 1:8 and the maximum height is now 75 mm, although the limit was previously 100 mm and some old ramps still exist. There is a tolerance that needs to be considered of +/- 12.5 mm, therefore the minimum laden ground clearance of any vehicle is required to be 120 mm.
75mm is near enough 3 inches.
100mm is near enough 4 inches.
No wonder we're in trouble.......
