How fat is your car?

So what have we proved here? It has been bemoaned a million times before that all the stuff in cars is too heavy and we should just get rid of most of it, but seats are useful for sitting on, airbags are useful for stopping you dying horribly, and parcel shelves are useful for shelving parcels (actually, has anyone ever actually put a parcel on a parcel shelf?). TG's 207 Superleggera is, essentially, useless as an everyday car, and not any quicker around a track. No question that many components could, and should, be made lighter - seats, particularly, are reaching a worrying level of heft - but that's a job for manufacturers, for suppliers, for people with computers and qualifications. Not idiots with hammers.
