most remote starts come with a number of safety features, it is quite easy to wire them up that way. The 50 dollar cheapie I put on my wifes jeep had a wire which was used for neutral or park sense, it is quite easy to wire this up in series with another sense for the parking brake since our solaras already have a factory switch in their.
just takes some wiring creativity. Don't get suckered into spending big bucks for a big name unless there is another feature you really wanted.
her rattler system has door lock/led/programable run times and many more features.
best of all installation was zero dollars and only took a couple hours at best.
