Any opportunity you get to learn should be grasped with both hands. Be it sitting alongside another driver, watching an in-car video or comparing data, any opportunity to compare and contrast gives you the opportunity to expand your knowledge.
You may find the driving styles offer no comparison but in that case you’ve at least learned there is another way to do it. You may find a new technique to try or an answer to a problem thats been bugging you.
Keep comparing and keep learning.
