Most super cars are not comfortable ride,s no matter how many luxuries they have, NO supercar that's built as a trackday car is a comfy ride, they're built to be stiff and rigid.
This is not necessarily true these days. Supercars have been getting easier and easier to live with. The F430 I drove the other day was entirely civilised (until you put your foot down). The ride is firm, but is far from being in back breaking territory. It's firm in a competent fashion, in a way that inspires confidence. I haven't driven the newer 458, but my friend says that the ride is even more comfortable. In any case, you can put these cars in different modes depending on the situation. You're on a track? Put it in Race mode and it'll firm up the suspension and shift faster. Cruising downtown? There's a mode for that.
You also have to remember that these cars are very light. If you want to make a land boat feel button-downed at high speed, yes, you are likely going to end up with a harsh suspension. But do the same for a light car and the suspension can be more compliant. Lotus cars always receive high praise for their suspension setups. It's no coincidence since their philosophy is "simply, then add lightness".
It's silly to dismiss the P1's ride since no one has driven one yet. Also, if it's being built as a car that you can take from the factory to the track, then you should be able to tune the suspension to your taste.
