My experiences with Sales in the driver's seat have been pretty bad.

One Sales exec thought it was hilarious to petulantly insist that our products be "zero cost, perfect, and shipping yesterday", dismissing out of hand small stuff like iron triangle, budgets, P&L, schedules, etc.

Another Sales exec, troubled by our excessive salaries (read: below market), denigrated our dev and ops teams by saying "All y'all do is type on the computer all day. How hard could that be?"

Etc.

(I don't know that engineering lead orgs are any better, overall. I've yet to experience the mythical balanced combo Sales, Engineering, and Support org.)
