Yes it's all about keeping CO low, rather than smothering fellow motorists, but perhaps one of those exhaust valves can be made to work at higher speeds where it will be useful.
Hmm... you'd likely want the exhaust sealed where it goes through the rear panel.
Not so easy..?

The lowest pressure will occur along the sides of the vehicle, not the rear.
Exhausting to the rear requires that zero leakage occur at the trunklid (boot) seal, and seal between trunk and rear seat/cabin.
It's the reason NASCAR demands side pipes to dilute tailpipe gases which could be inhaled during 'drafting.'
