Edward Lapham was absolutely right in his June 7 comments regarding the lack of product planning in eliminating passenger-door locks ("Keyless doors put a dent in chivalry"). It's an example of product design that ignores good taste, civility, even safety.
Let's dwell on that cold morning Lapham mentioned. Batteries do go dead, especially in really cold weather - weather in which you may need the shelter of a vehicle to survive.
And how many times do we need a second lock if the driver's side lock is broken or frozen?
If someone I knew was injured or frostbitten for lack of a passenger-side lock, it would be one of the few times I would consider a lawsuit.
