The question of whether it's a courtesy to allow a speeder to pass or if it's rude to drive the speed limit and not move over can be subjective and depends on the specific situation and local driving culture. Different people may have different opinions on this matter.
In general, there are a few considerations to keep in mind:
Safety: Safety should always be the top priority while driving. If someone is driving at a dangerously high speed, it may be better to allow them to pass to prevent potential accidents. Similarly, if you are driving at the speed limit and someone behind you seems to be tailgating or driving aggressively, it may be safer to let them pass.
Local Laws: While driving at the speed limit is legal, some places have laws that require slower-moving vehicles to keep to the right and allow faster vehicles to pass on the left. So, in those areas, it may be considered courteous to move over if someone wants to pass you.
Flow of Traffic: In some areas, drivers tend to go with the flow of traffic, which might be slightly above the speed limit. If you are driving at the speed limit and the majority of other drivers are going faster, it might be safer to move over and let them pass rather than disrupt the flow of traffic.
Staying Calm: If you encounter an aggressive driver who wants to go faster than you, it's essential to stay calm and not engage in any road rage or dangerous maneuvers. It's better to let them pass and continue driving safely.
Ultimately, it's essential to strike a balance between following the law and ensuring safety on the road. If you are driving at the speed limit and feel comfortable doing so, you can continue at your pace, but always be mindful of other drivers and consider the situation around you. If someone wants to pass, it may be courteous to move over if it can be done safely and without violating any traffic laws.
