Smart cars are primarily designed for city driving and have a limited range of long-distance travel. The electric version of the Smart Fortwo, for example, has a range of around 58 miles on a full charge, so it may not be suitable for long-distance travel. However, if you're planning to travel a longer distance, the gasoline version can go for longer, but it's still not meant for long-distance travel. The small size and limited cargo space of the Smart Fortwo may also make it less comfortable for long trips.
