Unless it’s a large speed change (50 to 30 for example), why are you braking? A 5mph change you can usually just take your foot off the accelerator and coast down to speed. It saves fuel, wear on your brakes, and helps prevent traffic from getting backed up in a wave of braking.
That’s potentially where the bewilderment comes from, they see brake lights and because people follow too close, they immediately brake much harder than you did because they can’t tell how much you’re slowing down or if you’re stopping.

You can still search between dates, but not from the advance search page directly. After you search, if you hit “Tools” it let’s you choose a date range.
