How about in the snow? How about a road with random 2-inch-high debris? How about a road with lanes of uneven pavement? And how's that air conditioning in the F1? Great for transporting kids too.
The F1 is designed to do exactly one thing exceptionally well, at the expense of practically everything else. It is the opposite of flexible.
And none of that will matter after the first time you drive over a 6 inch rock
Well, I can't say that I like cars or enjoy driving them, but the biggest advantage of a car compared to a bike is its roof - at least, when it rains.
I found this a bit confusing. Why is that, do F1 races have a speed limit? I openly admit my ignorance about F1.
The "Formula" in "Formula 1" means there are certain constraints (i.e., the formula) to how you can design your car. Very quick illustration, check out the buzz on the new F1 car spec for next year. It is already touted to be faster than this year's cars mostly because of aero changes.
Even easier illustration: the current (and I assume all future) spec has this halo whose sole purpose is to protect the driver. It's a ~7kg frame that's basically dead weight to the car. You can remove that and instantly gain maybe a few seconds of laptime at the expense of safety (I am in favor of the halo's presence, btw.).
The spec aside, the rules and regulations also try to enforce a competitive line-up so they regulate budget and, next year, wind tunnel testing time. So in theory if teams had carte blanche for car R&D we can have faster cars. But they won't be F1-compliant so they lose by default.
F1 cars are mostly optimised for massive aerodynamic downforce and lightness, which allows for unholy levels of braking, acceleration, and cornering speeds, but eventually the downforce hobbles top speed.
The LMP (Le Mans) formula of a couple of years ago has heavier cars with higher peak outputs, but lower downforce. They're slower around an F1 style track because their cornering and acceleration suffers due to the extra weight, but they have a higher top speed if they're on a long straight.
F1 race cars are literally the least flexible cars available. They are designed for exactly one type of racing and there is hardly anything you are allowed to configure the way you want. There are cars with higher top speeds than F1 cars, and cars that accelerate faster. A $2k second hand Honda Civic will beat the crap out of an F1 car around a gravel track. F1 cars aren't even the fastest design for racing on F1 race tracks. F1 cars are only good for one thing, and that is winning F1 races.
