I'd like to rephrase the "someone is always stronger/faster" into "we all have our limitations". Identify YOUR limitations and make decisions and preparations so that those limitations doesn't kill you.
I drive a lot in a state with a lot of bad drivers, plus an Army and AF base with a bunch of 19-yr-olds with their first brand-new trucks and sports cars. Most sections of the freeway have three lanes.
The right lane is taken up by the people driving too slow and the ones getting on and off the freeway, often on their cell phones or texting.
The left lane is full of people who think the speed limit doesn't apply to them, the ones who only slow down when there is a pair of tail lights four feet in front of them, and the ones trying to outrun the red/blue lights flying along behind.
The middle lane will get me there a bit slower, but still in good shape. Getting to my destination in good shape beats most of the alternatives.
