Recently, Tesla announced a Performance Plus Package for European buyers. Each item in the package may be purchased separately, including parking assist. With over 4000 Tesla S vehicles produced this year, there should be some way for Tesla to do the right thing and make this important, highly desirable parking assist option avaiable to USA "S" owners ASAP. Hopefully, it will be a Tesla Service Center install at a reasonable price point. Your comments on this matter would be appreciated.
