Für alles andere gibt es Autos. +Klar, in den Städten sieht das ein klein bisschen anders aus. Zum Beispiel hier in Halifax gibt es schon durchaus ein Halifax Transit Netz. Dieses Umfasst Busse und Fähren. Die, die verfügbar sind, fahren auch sehr regelmäßig. Aber eben nur im Großraum der Stadt. +Will man schon etwa 20-30km außerhalb etwas anschauen kommt man an einem Auto nicht vorbei. + +Nun mag man denken: Okay, ist jetzt vielleicht auch nicht die ökologischste Art, aber wenn das eben so ist, dann wird man ja auch ganz gute Möglichkeiten haben an ein Auto zu kommen. +Wir haben in den letzten Tagen so einige Überlegungen bzgl. Auto gemacht. Es ist so, dass wir ab Ende April bis einschließlich Juli auf jeden Fall in Newfoundland uns aufhalten wollen. Sprich wir fahren von Halifax bis nach Cape Breton, von dort mit der Fähre nach Newfoundland und dort vom Ferry Terminal zu unserer nächsten Unterkunft nach Brighton. + + +--- + +Der ursprüngliche, blauäugige Plan lautete: Wir könnten in Halifax ein gebrauchtes Auto kaufen, in der Zeit bis Sommer, evtl. bis Ende August, nutzen und danach wieder verkaufen. +Bis man sich mal mit der Thematik etwas genauer auseinander setzt. + +Wie auch in Deutschland, braucht man hier eine Autoversicherung. Diese wird schon benötigt bevor man das Auto kauft und auf sich zulässt. +Das erste Problem das wir dabei nun erkannt haben, dass es je nach Province unterschiedliche, rechtliche Anforderungen an die Versicherungen gibt. Es gibt Provinces wie z.B. British Colombia und Alberta wo es eine staatliche Autoversicherung gibt und fertig. Kein Wettbewerb, kein langes Suchen. Webseite, buchen, fertig. +Jetzt ist es in Nova Scotia eben anders. Hier gibt es einen "freien" Markt, ähnlich wie in Deutschland. +Nachdem man ein paar Insurance Broker_innen mal geschrieben hat, dass man gerne mal ein Quote, also ein Angebot hätte, wurde schnell klar, dass viele der Versicherungen zum einen nur nationale Führerscheine akzeptieren und zum anderen mindestens 12 Monate laufen (und bezahlt werden müssen). +So entwickelte sich die Idee den deutschen Führerschein gegen einen aus Nova Scotia zu tauschen (da dies sowieso bei einem Aufenthalt von länger als 90 Tagen Pflicht ist). Das zweite Problem was sich dann aber abzeichnete, dass wir ja den Bundesstaat bzw. die Province ja wechseln wollen. Sprich die meistens Versicherungen können nur für die jeweilige Province abgeschlossen werden. Das selbe gilt für das Fahrzeug. +In unserem Fall wäre das also so, dass wir in Newfoundland das Auto bei der Motor Vehicle Registration nach Newfoundland umschreiben lassen müssten. Mitsamt dem Führerschein (Nova Scotia Führerschein -> Newfoundland and Labrador Führerschein) und die Versicherung kündigen (was bei einer außerordentlichen Kündigung unter 6 Monaten Strafzahlungen beinhaltet) und eine neue abschließen. + +Alles in allem wären die Kosten hierbei sehr hoch. Das Umschreiben/Tauschen des Führerscheins kostet jedes Mal, das Auto natürlich initial, die Steuern des Autokaufs (welche erhoben werden wenn das Fahrzeug registriert/zugelassen wird) und die Versicherungen. +Bei den Versicherungen reden wir hier nicht von deutschen Preisen einer Haftpflicht von etwa 300-700€ (je nach Fahrzeug) sondern von etwa 200-400C$ (ca. 130-270€) pro Monat. + +Schlussendlich haben wir für uns nun erstmal entschieden den Weg über ein Mietwagen zu gehen. Dort ist die Versicherung inkludiert und Mietwagen können frei über Provinzgrenzen und sogar in den USA genutzt werden. Klar, dass Geld das wir hier zahlen ist natürlich "weg" aber der Mietwagen kostet uns nun 3 Monate etwa doppelt so viel wie uns alleine die Versicherung für ein eigenes Fahrzeug gekostet hätte. + +Der weitere Plan danach ist, nach aktuellem Stand, Mitte Juli wieder nach Halifax runter zu fahren, das Fahrzeug dort wieder abzugeben und mit dem Zug von Halifax nach Montréal zu fahren. + +Züge sind in Kanada noch weniger vorhanden als Busse. Es gibt aber eine Coast-to-Coast Verbindung welche von Halifax bis Vancouver reicht und man an nahezu allen Großstädten im unteren Kanada aus- und zusteigen kann. +Wir wollen diese Option als Alternative zum Flugzeug zumindest bis Montréal mal nutzen und erhoffen uns dabei viel von der Landschaft in New Brunswick und Québec zu sehen. + +Führ die Reisen in den oberen Landesteil, was wir durchaus auch anstreben, werden wir wohl oder übel auf das Flugzeug setzen müssen.
