What did he mean?

I’ve been talking to this guy and every few weeks I have something to rant about. I give him a fair warning prior though. I’ll let him know that it’s a rant and he always tells me go for it. I did that today and he told me go for it. I asked him why he always wants to hear my rants because no other guy would want to. He told me that’s what he’s there for and said “I’ll be driving this whole time so I’ll be here.” He’s heading like 5 hours away for the weekend. I took it as he’s riding along in the car and has nothing to do so he’ll be here. He hasn’t replied to it and it’s been 4 hours, so now I’m thinking he actually meant he wants to hear it but he’ll be driving so might not respond but he’ll be there??? Like the second one makes more sense right?
