Unbalanced tires, broken or lose suspension components. Have the tires rebalanced and go from there. if that dont help check the tie rod ends, upper and lower ball joints. Sometimes mud or ice can build up on the inside tire rim throwing off the balance.

Well, on part is the engine. It makes so much heat, there is a fan in it to cool it down. That is why whenever you start a car, it shakes. That is the fan turning on.
If your car shakes while underway, your tires have worn incorrectly from misalignment. If it shakes while in park or not moving, your engine is misfiring.
I would start with wheel balance but the front end steering and suspension needs to be checked also.
If a car shakes during acceleration the brake rotors may be damaged. If the rotors are damaged they will be unstable as the tires rotates making the whole car shake.
If a car shakes and loses power when idling it can be the spark plug. If a spark plug is fouling, it can cause power losses.
Engine miss.
Car shakes when I put the brake check
When the engine light comes on and the car shakes at the same time, it could be the spark plugs or ignition coils are faulty. Misfiring is causing the car to shake.
Disk brake rotor is warped
Drive shaft is going out
NO! Depends on your definition of safe?
