I have and have had some really nice daily driver cars, including a '12 CTS-V, '08 Yukon Denali, current '13 Lexus LX570 (Land Cruiser luxury land yacht), etc. I've also driven a '13 BMW M5 for a week including a 800 mile road trip.
The 2016 Camaro 2SS with 8-speed automatic, dual-mode exhaust, and magnetic ride is an OUTSTANDING daily driver. It is so smooth, comfortable, and fast. Probably one of the best highway cruisers I've been in. Gas mileage is incredible too, easily over 25mpg doing 80+mph. Car doesn't go over 2,000rpm until you're going above 90mph.
The 2012 CTS-V was a close second to the Camaro in highway cruising, but it would be lucky to get 18mpg at a fast cruise with the six-speed automatic.
Really the only downside at all is visibility, but it's really not bad at all if you adjust the mirrors and seat positioning correctly. Blind spot monitor helps as well. View out the back isn't great, but good enough. Not to mention, you don't have to worry about what's behind you as it's highly unlikely anyone is going to catch up.
