You're right! There are approximately 50 cases a year worldwide where cars are used as weapons, killing about a dozen people. Meanwhile in the US alone there are 30,000 gun deaths a year.
But since you are upset about the 50 and not the 30,000, let's put more regulations in place.
Let's require everyone to get training before they are allowed to drive a car, including how to operate it and how to obey traffic laws.
Let's test everyone before they ever get to drive by themselves, so we know they are safe drivers.
Let's require a license, and require regular renewals of that license, along with more testing.
Let's require insurance for those cars, so that 1) there is a way to pay people who are harmed by your car and 2) provide incentives for you to drive safely.
Let's require registration of each car so we can keep track of them for purposes of things like recalls and theft.
Let's require BACT safety features in each car, like brakes, pedestrian crumple zones, airbags, horns, brake lights and bumpers.
Let's create traffic laws, signage, traffic lights and traffic controls to increase safety.
Let's create a police force dedicated to enforcing traffic laws.
Let's ban cars in places like the interiors of airports, courtrooms, hospitals etc and clearly delineate where they are allowed to be operated - and be parked.
I am sure you will agree that all these are necessary.
Then we do all that for guns - and perhaps we can get that US total down to, say, 10,000.
