I think you'll be fine, I know people who got driver's license around that age (even for motorcycles which to me sounds riskier) and they're fine. Reaction time may be not be at its peak in 40's (doesn't mean it applies to everyone), so you may want to take it easy. For some people fear is the biggest barrier and that's what kept them from going for it (not sure where it comes from though). Good luck!
