Average travel time seems to be about 25 minutes in the US (https://www.census.gov/prod/2011pubs/acs-15.pdf) so I suspect that for most of the driving that people actually do the Model 3 will be more than adequate. The problem is what counts as a day trip in the US is much further than in the UK. Of course you could just rent an ICE car for longer journeys. I have a colleague in Raleigh NC who rents a car when he drives to Florida (long weekend, not day trip) even though he has a perfectly good car of his own. His reasoning is that he can often get special offers so it is cheap, reduced wear an tear on his own vehicle, and if an incident occurs he won't have much to do and no impact on his car insurance.
