Tuxedo-clad Gria Jacobs has been a chauffeur in NYC for three years, she said from behind the wheel of her Mercedes. For her, looking good while driving is easy. Parking is hard. Every year, Jacobson has to shell out $3,000 to $4,000 in parking tickets, the painful price of doing business. And she fears a new DOT program designating public parking spaces to car-share and rental companies means fewer legitimate spots for her — and possibly more tickets.
