The sun's at the wrong angle to clearly see how you cut the lid. 3 or 4 slots 2" wide would suffice. You might fill the hole with a sheet of rubber from an old inner tube (I think trucks still use them).
A vented spoiler like they use to keep dust off the back window of a station wagon might keep the exhaust fumes out. Or a tail-pipe extension that curves down into faster moving air. Don't be lazy about carbon monoxide ha ha.
