* Size and Safety: Smart cars are incredibly small and lightweight. This makes them vulnerable in accidents with larger vehicles. The lack of substantial crumple zones significantly increases the risk of serious injury in a collision.
* Limited Storage: The tiny cargo area severely restricts the amount of luggage, supplies, and tools you could carry for a cross-country trip. You'd likely need to rely heavily on roadside assistance and pre-arranged accommodation.
* Mechanical Reliability: While generally reliable, a 15-year-old car will have some wear and tear. The risk of a breakdown in a remote area is significantly higher than with a newer, more robust vehicle.
* Highway Driving: Smart cars are designed more for city driving. Maintaining highway speeds for extended periods could strain the engine and impact fuel efficiency. Strong winds could also pose a significant challenge.
* Fuel Efficiency (while seemingly a positive): While their fuel economy is good, needing frequent fill-ups will significantly increase the travel time and logistical effort of the trip.
* Comfort: Long-distance driving in a Smart car would be uncomfortable for most people. The small cabin offers limited passenger space and legroom.
In short, while it's *possible*, a cross-country trip in a 2008 Smart Car is highly inadvisable. It would require meticulous planning, significant preparation, and acceptance of a higher-than-average risk of mechanical failure and accidents. A more suitable vehicle would be far safer and more comfortable for such a journey.
