Right lane ends...

...exit only.  That's what the sign says.  The sign does NOT say, "By all means continue driving as if nothing is changing."  The sign DOES NOT say, "The person driving next to you will slam on their brakes to let you over at the last possible second because you are an ignorant, illiterate douche bag."  Go ahead.  Flip me off.  Fuck you right back.  I hope you eat guardrail.
