Cách sử dụng
The expression "where the rubber meets the road" means the most important part of something. It's the place where things really happen or where something really matters. For example, in a car, the most important part is where the tires touch the ground because that's what makes the car move. In a business, it might be where the actual work gets done or where the money is made. So, if you use this expression, you're talking about the part of something that really counts, the part that can make or break it.
