driving is dangerous so it should be unlawful.
And it is legal to have a 10 year old as a passenger in a car which is what happened in this case on the climb.
It's more because it's El Capitan. It's a special place. I get why climbers feel attracted to it but it's more important that it be protected than people, in ever increasing numbers, get the pleasure of climbing it. Look at what's happening at Everest. The feat's been accomplished, no need for everyone else to do it too.
