This might just be a minor point, but games are not only created with "how they feel" in mind - there are many more variables to consider: What are the trademark features of the game? Gameplay limits and bounderies? How good should it look, perhaps in order to give it an advantage (in PR terms) over its competition to achieve more sales? etc.
It's at the end a triangle of visuals / framerate / logic complexity (AI, physics, gameplay) and a studio has to decide which compromises it makes to get the best out of these 3 areas. A game dedicated on framerate and logic complexity will make shortcuts in the visual department, a game on the opposite end the other way around. That's why they are called trade-offs. You're effectively trading-off "gameplay aspects" for either graphics or framerate, "feel" (framerate) for visuals or any other combination.
Just because a game is 30fps does not mean the game wouldn't feel or play better at 60fps. It's more likely that the team felt the "tradeoff" of settling for 30fps was "good enough" for the majority as long as they can play the hype card of having the prettiest racing game on the market. If they can get more sales by doing this, fair play to them.
The biggest issue I have with 30fps games is that games are being sold on the premise of foremost graphics. If the majority of devs go for graphics over framerate, it makes it more difficult for other devs to ever seriously consider 60fps because it would probably mean their game would look substantially worse (in screenshots) than the competition, perhaps resulting in less sales ultimately. That's why I think it's great that sites like DF devote their analysis to framerate - a feature in games that can't be seen in 30fps Youtube captures or screenshots, but is an integral part of any game. It's important to raise this awareness IMO.
I like to believe that especially on this forum, where the majority of posters can be considered to be "hardcore" to "above average" gamers, we don't want our games to be dumbed down and sold on the premise of better graphics at any cost. This might be a bit harsh considering I'm sure EvolutionStudios made a terrific game, but there should also be a line at some point that should not be crossed.
