Normally, there’s a lot of stories involving vehicles getting into accidents on weekends where the weather is less-than-optimal. But this weekend, when driving conditions could honestly not get much better, there’s been far too many disturbing reports of vehicular violence for this editor’s taste. A jogger was struck and killed by a driver at 14th Street and Constitution Avenue NW early yesterday morning, closing down the surrounding area to traffic for a time — and details are scant, to say the least. Then there’s this charming story of a Montgomery County woman who attempted to run down police officers on Georgia Avenue — twice. Two accidents in suburban Maryland which killed two certainly lend color to our nightmarish vision of a Mad Max-style highway dystopia. On a related note, MPD picked an interesting weekend to admit that the equipment it uses to measure suspected drunk drivers’ blood alcohol level is completely unreliable. Now, if you’ll excuse me, I’ll be canceling my plans for a nice, relaxing Sunday drive.
