Maybe, but the car manufacturers have different goals to achieve in today’s eco world we are in - that of selling a car with lower CO2 data of which the weight of the car is a major contributing factor.
Hence almost all base cars today a low weight puncture repair tube of gunk which obviously saves a good 20kgs.......and it’s that base car that is used to measure the car’s CO2 data.......
