Sir, – Simon Comer (January 24th) advises drivers with back ailments to slow down when travelling over speed ramps. As someone who suffers frequently from sciatica pains, I'd like to point out that this approach still comes with its ups and downs. Instead, I've found that any speed ramp problem can be overcome by simply getting over it. – Yours, etc,
