Downtime

On a related tack, reader Sam Evans writes on Downtime's idea for a Braille speedometer.
"With reference to the reader who criticises the Braille speedometer because 'you would have to take your hands off the steering wheel'. Has he or she not thought of having the Braille output as part of the steering wheel? This would enable the blind user to have all kinds of useful information at their fingertips, not just the speed."
