Not the steering wheel shake itself, however what is causing the steering wheel shake, can certainly be extremely dangerous and potentially cause you to lose control of the vehicle. **GET IT CHECKED OUT BEFORE THAT HAPPENS**
What make the steering wheel shake is the tires that need wheel balance.
A shake in the steering wheel or car itself which occurs and/or increases as vehicle speed increases.
Wheel balance

Yes A VERY common concern is steering wheel shake due to ice in the rims
Yes, it is possible. Any loose/worn front end part can cause steering wheel to shake.
Most shaking in the steering wheel on ANY vehicle is caused by balance problems. The tire can be out of balance, the wheel can be bent or the axle (half-shaft) can be damaged and out of balance.
Tire out of balance or bent wheel.
If the bent rim is mounted on the front you would feel the steering wheel and front end shimmy or shake depending on the severity of the bend and speed of the vehicle. If the bent rim is mounted on the rear you would feel the vehicle shaking but not in the steering wheel.
steering the wheel
im guessing it has something to do with velocity and road conditions. yet again, if i'd imagine that a steering wheel shouldn't shake.... that can't be good.
