Letter: Safety measures after motor racing's black weekend, and how Senna might have survived

Sir: The safety of Formula One motor racing could be improved if the FIA lifted the restrictions, imposed only last year, on the width of tyres and the size of aerofoils. This would improve the cars' road-holding without in any way reducing the driver's role. (It would not drive up the cost, either.) They could even review the ban on 'ground-effect' aerodynamics.

Yours faithfully,
