求助~~~

M: Kay, the weather report says it's going to pour today. You should probably put your bike in the garage before it really starts coming down. W: Hum, why bother? It’s been true a lot worse, it still works just fine.


这是老T中PartA的一道题， 后边“It’s been true a lot worse, it still works just fine.”  应该怎么理解呢？
