Can't, not at 30mph.

There are others on the road who might not be limited by your 30MPH ideal.

Not to mention it is perfectly possible to have a nasty crash at 50KPH.
Especially if you hit an object moving towards you, which greatly
increases the kinetic energy released. But you forget, Savageduck -
Macaw is a special snowflake. His life and physics itself works
different for him.

The kinetic energy is doubled, but halved again as it's dissipated into both cars.
