It's fine and good for everyone to claim that the driver must keep alert constantly and it's their responsibility. However, this feature is inconsistent with that statement as it is damned near impossible for most people to stay engaged and alert when they are not actively engaged in a process. This is a known failure of the human brain and in fact is the reason that on road trips I don't use cruz control and tend to speed because when I'm engaged, I'm paying attention.
