My wife is strictly a fair weather biker. I tried to get her to bike somewhere with me, but the weather wasn't favourable, so we drove. I got us lost giving her directions.
"I thought you said you knew where we going."
"I know exactly where we're going, I just don't know how to get there in this thing. Oh, wait, this is it. Turn left here."
"I cannot take my car on the greenway!"
"Well don't tell me I don't know where I'm going, when you just don't want to follow my directions."

So, yeah, there may be such a thing as too much time on the bike.
