No one is saying that. Perhaps we should strip out those seat belts that crept into our cars since the 50's and 60's too? After all, nothing but a firm grip on the wheel or a lap belt was good enough in the 'good old days', why fit those silly inertial reel 3 point belts now? Should we go back to the halcyon days of non gripping crossply tyres too? After all, they were a new fangled and expensive 'safer' option only on the higher performing cars from the mind 60's. Why anyone with an older car should fit such safer tyres is beyond me when crossplys were good enough back when it was built. Oh that's right, we have vasty more traffic on the roads, the vehicles around us are almost invariably far bigger and heavier than us now, and unleaded petrol thanks to the increasing ethanol content is a rather more difficult stuff to extinguish than leaded stuff. An inertia switch one an electric fuel pump is cheap and unobtrusive primary safety. The fact they didn't routinely fit them in the past is utterly irrelevant as the technology didn't exist to build cheap and totally reliable ones for mass usage in the past.
