Higher g's produced at higher speeds are harder to survive.
Because at higher speeds you have more velocity than at lower speeds transferring more energy to make a bigger crashing causing more damage.
Car crashes at higher speeds are more dangerous because the impact forces increase as the speed increases. Higher speeds result in more kinetic energy, which translates to more severe damage to vehicles and occupants upon impact. In addition, it becomes harder for drivers to react quickly and control the vehicle at higher speeds, increasing the likelihood of a crash.
Because you have more velocity at a higher speed, which transfers more energy, causing a more dangerous and hard crash. Kinetic energy is 1/2 m v2 so the energy is the square of the velocity, i.e. twice the velocity, four times the energy, and so on and so forth.
A bike helmet is designed for lower impact speeds and lighter weight, providing protection for falls from bicycles. Motorcycle helmets are heavier and offer more protection for higher impact speeds and potential crashes at higher speeds. Motorcycle helmets also typically have a visor for additional protection.

Not use their high beams and drive dramatically lower speeds.
In a liquid, molecules have a wide range of speeds due to their random motion. The distribution of speeds follows a Maxwell-Boltzmann distribution, where most molecules have speeds around the average, but some have significantly higher or lower speeds.
Using a higher gear ratio in a vehicle's transmission system can provide better fuel efficiency and lower engine RPM at higher speeds, but may result in slower acceleration. On the other hand, using a lower gear ratio can improve acceleration and towing capacity, but may lead to higher fuel consumption and engine noise at high speeds.
Steering will "wobble" at higher speeds and sometimes when braking. General looseness in steering.
Because the higher voltage would be dangerous domestically.
sounds like you need a wheel balance
Changing the number of impeller blades can affect the flow patterns, turbulence, and efficiency of a pump or turbine. Increasing the number of blades can improve efficiency at lower speeds but may lead to more turbulence and cavitation at higher speeds. Decreasing the number of blades can reduce efficiency at lower speeds but may result in more stable operation at higher speeds.
