It's possible for the faithful to obtain their Ash Wednesday blessing at curbside. "Churches all over the country are making it easier for parishioners pressed for time to get their Ash Wednesday blessing... via the drive-thru." At some churches, the wanderer's blessing is available in the morning, at others in the evening. At least one commentator is unimpressed. "You could conceivably get the mark of the cross on your forehead while still gulping down the breakfast burrito and hash brown you picked up at the last drive-thru."
The whole point of Lent is sacrifice and reflection. Obtaining the symbol at little effort strikes me as missing the point.
