Avoid dry meadows for parking
If you want to put your car in a nice spot, some people resort to meadows, woods or fields, but these are usually dried out in summer. Most people are probably not aware that components such as the catalytic converter or the exhaust system reach temperatures of around 600 °C after just a short drive. The fire risk is therefore enormously high, especially during hot spells. The insurance companies don't like it either: motor vehicle liability covers damage to other people's vehicles, but comprehensive insurance can reduce the coverage due to gross negligence. If the fire brigade is needed, it is very likely that they will also send you a bill.
Heat damage on the road
Approximately 30% of German motorways have a concrete surface. However, this is not able to withstand the heat. Sudden and prolonged high temperatures cause the surface to bulge and, in the worst case, crack. These so-called "blow-ups" are extremely dangerous, which is why motorcyclists should avoid concrete surfaces altogether in summer.
On an asphalt surface, there is no danger of blow-ups due to the soft tar. However, the tar deforms due to the high heat load, which can lead to deep ruts. This also increases the risk of aquaplaning in the event of a summer thunderstorm.
