On the second one you need to change 'consist' to 'consists.'
You need to use 'on' instead of 'in' also when you say "A human is the best driver in the "selfishness" road.
You need to say 'accounts' instead of 'account' on the last one. You may want to say 'the best' instead of 'best' as well. It's not wrong, it just makes more sense.
But everything else is perfect. :)
