A touch of frost

[mtbc]

Despite recent Spring-like weather it was below freezing when I left the house this morning; I let the car warm up for a few minutes blowing air to clear its windows. The frost may have surprised the daffodils at least as much as it surprised me.

In Douglas Adams' Dirk Gently's Holistic Detective Agency mention is made of the possibility of a car with heated side mirrors. To me such a thing seems achievable and desirable for days when those mirrors are obscured by frost: it would save on spraying deicer.
