mmyeah, but my Insight does have a sealed fuel system and spillage recovery system and still it smells a tiny bit.
ANY car will have to cope with the vapor in the tank expanding and receding with temperature and other factors.
I could smell the ethanol. It did escape somehow. And it did less so when mixed with a tiny bit of water, even though the ethanol content was higher.

The tiny bit of water does not affect the combustability of the fuel. The fact that the fuel I tank is hydrogenated and still yields record FE in my car proves that.
Whisky is mostly water, yet even that burns.

I tested both hydrogenated and unhydrogenated ethanol, both work for me.
Please do test a hydrogenated blend and then come back to say it does not work, if it doesn't.
I value your opinion, but unless you tested with hydrogenated ethanol it is just an opinion.
