Hi there and welcome to the community
Without sounding like preaching, you could allow responsibility and respect for others to guide you to keep within the speed limits. Speed limits are put in place for the safety of road users.
I think your mind and thoughts are playing games with you, not the Law of Attraction. Maybe you can tell yourself that by keeping to the speed limits, you are respecting the lives of others and the greater good.
Hope this helps and wish you much peace and joy
