What if I don't listen to my girlfriend and just going past the speed limit on the highway?
Driving fast could cause an accident?
Yes, I hear that, but I don't care.
You should always drive carefully considering the conditions. If it's all clear with light traffic, you can adjust accordingly. Make sure you do your best to avoid causing accidents.
Yeah, I just want to go the speed limit. I know I'm anxious to move forward faster, but I'm feeling myself not wanting to be a danger to others.
You should respect your girlfriend's wishes to slow down a bit on the highway. If you make her uncomfortable in while driving she may just avoid going places with you.
