Transporting bike in car

Hi guys, had a slight issue when transporting my bike the other day. Bike was laid on it's side for an hour maybe 2 hours, after taking the bike out and then getting on, the forks felt quite firm for about 10 minutes or so. After that they felt fine again. So my question is firstly is this normal, perhaps oil needs to settle in the fork lowers? And secondly is it ok to leave the bike in the car on it's side for a prolonged period?
