Speed kills

'Speed kills, slow down' many times have I heard this being thrown at us as a people in reference to our cars and that speeding puts us all at greater risk. This is true but the statement rings untrue to someone who knows what really kills in crashes. What kills people in car crashes is stopping quickly, newtons law ( 'an object will keep moving in one direction until stopped' ) is what kills people. Think about it if your moving at 100kph you have a fairly large amount of energy if you crash into a brick wall you stop very quickly and (if you have one on) your seatbelt stops you making a dramatic exit from life, the issue is that everything inside you wants to keep moving forward this somewhat poses some problems for the delicate organs inside you often ending in damage. Just to prove further that stopping is the problem not going faster think about now fast we are going to start with let me list a few things that affect our speed. ( assuming that we could have a fixed point in space-time to calculate our speed from) We have our global rotation, speed of orbit around the sun, ok yea pretty basic and now the slightly insane part, on top of those two we have our solar systems orbit around the galaxy then we have the galaxy's movement in relation to the other galaxy's and finally the total universal migration to the 'dead spot' of space and lastly general universal expansion rate. They all add up (and occasionally subtract) to the total speed. So saying speed kills is generally wrong but I guess it sounds better than 'stopping kills so don't crash' DFTBA
