It is ethical for Christians to operate motor vehicles?

Should Christian really be operating vehicles, knowing that they could be raptured at any time? I think it should at least be forbidden for Christians to drive or pilot public transportation such as taxis, buses, and airliners. Just think of the mess it will cause if the flight crew of a jumbo jet are Christians and Jesus decides to make his return when they are cruising at 30,000 feet with plane full of Muslims heading to Mecca!
